UV and Green Lasers

Image
Coherent Inc. has added the 355-55 UV and 532-80 green models to its AVIA line of industrial lasers. The lasers extend and improve the performance of microprocessing applications in microelectronics, photovoltaics and related industries. Specifically, the 355-55 features a high pulse repetition rate of 150 kHz, resulting in an average power of 55 W at 355 nm. The 532-80 produces 1-mJ pulse energy at a power of 532 nm, which, together with a maximum pulse repetition rate of 80 kHz, translates into an average power of 80 W. UV lasers are used for cutting flex substrates and thin printed circuit boards where higher lateral resolution are a critical consideration. The higher power now available from the 355-55 will extend these cutting capabilities to >200 µm flex and multilayer materials. The 532-80 green lasers are used for scribing films, drilling holes and slots, and cutting flex substrates that efficiently absorb green wavelengths including certain printed circuit board su

Five photonics trends for 2018

The year is ending, holiday reminders surround us, and after some opulent dinner it is time to think about what may come to us next year. A few trends in photonics such as lidar or additive manufacturing are obvious, others may be less apparent. Here are my picks for photonics trends that might be worth watching in 2018. 2017 was an incredible year for industrial photonics: Market leaders such as Trumpf and IPG Photonics posted double-digit revenue growth, and Coherent seems to do well with the purchase of Rofin Sinar. It is no surprise that fiber lasers conquered more than 40% market share, while the good news for excimer lasers may not be on everybody‘s focus. And thanks to EUV the good old CO2 laser has some new prospects as well. Behind many of the good numbers is a record breaking spending of almost $56 billion for equipment in semiconductor industry. The CEO of Carl Zeiss, Michael Kaschke, spoke of “the most successful fiscal year in the history of Zeiss,” backed by a 25% in

“In Industry 4.0, lasers provide a connection between the virtual and real world”

As scientific and technical director of Hanover’s Laser Center (LZH), Prof. Ludger Overmeyer works at the interface between research and industry. In our interview, he talks about trends in laser material processing, potential still to be exploited in process optimization, and his expectations for the conference LiM—Lasers in Manufacturing, which he will be leading from June 25 to 29, 2017, as part of the World of Photonics Congress. Prof. Overmeyer, as conference manager of LiM 2017, what highlights do you expect? Prof. Ludger Overmeyer: We have a very wide range of presentations this year by the most prestigious experts from Asia, the U.S., Canada and various European countries. Together, the presentations cover the entire spectrum of modern laser applications, from micro and macro processing to additive processes for metals, plastics and even biological tissue. Prof. Paulo J. Bartolo from Portugal will be giving a keynote presentation on tissue engineering in regenerative medi

Laser guide shoes prevent 'freezing' in Parkinson patients trying to walk

Freezing of gait, an absence of forward progression of the feet despite the intention to walk, is a debilitating symptom of Parkinson's disease. Laser guide shoes developed at the University of Twente (Enschede, Netherlands) and Radboud University Nijmegen Medical Centre (Nijmegen, Netherlands) that project a line on the floor to the rhythm of the footsteps help trigger the Parkinson's patient to walk.1 The shoes benefit the wearer significantly, according to the researchers. Walking problems are common and very disabling in Parkinson's disease. In particular, freezing of gait is a severe symptom which generally develops in more advanced stages. It can last seconds to minutes and is generally triggered by the stress of an unfamiliar environment or when medication wears off. Because the foot remains glued to the floor but the upper body continues moving forward, it can cause the person to lose her balance and fall. Lines on the floor Parkinson patients experience a uni

Concept Metal Products boosts production with second laser cutter

Image
Sheet metal fabrication specialist Concept Metal Products (Middleton, England) has invested in a second Kimla fiber laser system from laser cutting and metal fabrication equipment supplier MBA Engineering (Wetherby, England), after experiencing substantial increases in production from its first machine. Related: Polish laser cutting system manufacturer cracks the Western European market After installing a 10 × 2 m Kimla Powercut 4 kW fiber laser in early 2017, Concept Metal Products was so impressed with the speed and precision of the machine and the resulting cost savings that it installed a second system—a Kimla Powercut LF2040 6 kW fiber laser. Kimla's fiber laser systems have a small footprint to save valuable factory floor space and reduce costs per square meter, and cut to a 0.03 mm accuracy.

Ultrafast, high-intensity lasers improve understanding of chiral molecules

Image
The starting signal is given and two electrons speed off in opposite directions. The one that wins the race is barely seven attoseconds (7 x 10exp-18 seconds) ahead. The difference is so small that up till now it has been impossible to measure. Yet, that difference is caused by chirality, a hallmark of molecules that emit electrons. An international research team (INRS/CNRS/CEA/UPMC/University of Bordeaux/Weizmann Institute) made this precise measurement by directing an ultrafast laser beam at camphor molecules. Theoretical equations predicted the result, but as one of the authors of the research article published in Science explains, no one has been able to prove it before. You can get a good idea of what chirality is by putting a right-handed glove on your left hand: two identical shapes that cannot be superimposed because they are mirror images of each other. This property is common in our universe, from the smallest particles to huge galaxies. Although the physical charact

Do you undersrand your laser goggles are qualified

High-power ultrafast pulsed lasers are used widely for biomedical applications and imaging, materials processing, industrial micromachining and more. But many laser-eyewear products are not tested with ultrafast lasers and may not be providing adequate protection for the technical workers who depend on them. The main reason for this situation lies in the typical test procedures and standard measurements widely followed by eyewear makers to set their product specifications. Those methods use low-power continuous-wave (CW) light sources. As a result, they do not capture many potential hazards of actual high-power , pulsed-laser working conditions. Moreover, end users only infrequently test how their eyewear performs in particular applications prior to deployment. Scientists at the National Institute of Standards and Technology (NIST; Gaithersburg, MD and Boulder, CO) and Hood College (Frederick, MD) have published a study of 24 samples of protective filters used in eyewear from fiv

Laser light show scheduled to achieve Guinness World Records title

Image
To celebrate its tenth anniversary, laser light show and laser system design specialist ER Productions (Dartford, Kent, England) will attempt a Guinness World Records title for the largest laser show at Live Design International (LDI) in Las Vegas at 7:30 pm on Saturday 18 November on the LDI: Live outside stage. ER Productions plans to use over 300 lasers as part of a 30-minute laser showcase that will culminate in a seven-minute finale to achieve the Guinness World Records largest laser show accolade. The title attempt will feature a live performance from British DJ, Damian Gee, who will soundtrack the event at LDI, North America’s largest trade show for the live entertainment technology and design industry. Ryan Hagan, co-founder of ER Productions, said, "We opened our first US office in Las Vegas 3-years ago, 7-years after we started the company and the city has been very kind to us.  For our 10th birthday, we wanted to create a truly memorable laser show that people w

That laser pointer could be more dangerous than you think

Image
But increasing ease of use can bring with it the danger of misuse, whether deliberate or accidental. Concern is growing over the safe use of small, battery powered, hand held lasers. For example, there are now thousands of incidents every year of aircraft pilots being targeted by lasers from the ground close to airports, with some suffering serious eye damage. This wilful and illegal misuse highlights the potential for accidents too. Our eyes are highly developed to see in great detail and also in very low light , but these very qualities make them vulnerable to damage from light, too. Lasers are classified according to whether they present a danger to the eye, with classes 1 and 2 being safe in normal use, but how often do we check that a new media player has its correct "class 1 laser product" sticker? Dangerous lights At least the lasers in media players are enclosed. Laser pointers are designed to be free and to be seen. At low power, less than a thousan

How to choose high power green laser pointer? What should we pay attention to in the process of using?

Image
The green laser pointer is the most popular laser pointer on the market. Because green lasers are brighter and brighter than other colors. Most of the market is less than 50MW green laser pointer , and the price is very cheap. Such laser pointer Compact size, easy to carry, bright beam of light to indicate the effect class.Such laser pointer Compact size, easy to carry, bright beam of light to indicate the effect class. If you are a super laser enthusiast, or have research needs, other special purposes, then do not meet the low-power green laser pen, want to buy a high power green laser pointer . The problem is that high power green pointers don’t have a uniform price on the market. And many businesses use low power green light as a high power to cheat consumers So, what if we can choose a high power laser pen? Here are my years of experience:   1. If you’re rich and don’t care about the price, then Wicked Laser is your first choice. The product is exquisite, but the price i

Fun with VCSELs and the iPhone 8

The iPhone 8 is notable because it is the first iPhone that contains lasers --two to be exact. The iPhone 8 contains a lower-power vertical-cavity surface-emitting laser (VCSEL) pointing backward and another higher-powered VCSEL facing forward. If you own an iPhone 8, you are holding these lasers in your hand right now but probably never knew it. What do they do? First, they assist the iPhone 8’s camera to understand the scene the camera is viewing, and they assist with camera autofocusing. Second, the laser sensors assist virtual reality applications to understanding their physical environment, in the same way autonomous vehicles use lidar and cameras to understand their physical environment. Lumentum is producing the majority of the VCSELs that Apple is using in their iPhones, but Apple will also buy some additional VCSELs from other manufacturers like Finisar and II-VI. While the iPhone 8 is the first Apple smartphone using VCSELs, they have been used in a variety of other smart

Be careful of being slaughtered, 3W high power laser pointer can also be so cheap

Image
High-power laser pointer   sought after by everyone: 1W green, 3W, 5W Blu e  ... ...  3W is pretty high at the moment. High power often means high prices. And now on the market a variety of laser pointer, the price is uneven, so that we do not have a reference when the purchase price. Here, through my years of experience with my friends and the purchase and use of experience, combined with the current market corresponding prices, I would like to talk about my personal experience: What I like most is the blue high power laser pointer , I bought 3W, 5W, 10W, 30W (of course, now it is found that more than 5W are basically false power marked by the seller), 3W and 5W blue light which is the rise this year, 2017 is basically dominated by blue 2W, 3W, 5W is relatively less, but very expensive. I also because of the need, in early 2017 to buy a blue pointer 3000mw of around $ 400, but once lost while camping. Recently, I bought a new 3W blue on Lucklaser, and the price was $ 139 , which

Laser beams for superconductivity: Research sheds light on unexpected physical phenomena

Image
A laser pulse, a special material, an extraordinary property which appears inexplicably. These are the main elements that emerge from a research conducted by an international team, coordinated by Michele Fabrizio and comprising Andrea Nava and Erio Tosatti from SISSA, Claudio Giannetti from the Università Cattolica di Brescia and Antoine Georges from the Collège de France. The results of their study have recently been published in the journal  Nature Physics . The key element of the study is a compound of the most symmetrical molecule that exists in Nature, namely C60 bucky-ball, a spherical fullerene. It is well known that this compound, with the chemical formula K3C60, can behave as a superconductor - that is, conduct without dissipating energy - below a critical temperature of 20 degrees Kelvin, i.e. around -253 degrees Celsius. It has recently been discovered that K3C60 is capable of transforming into a high-temperature superconductor when struck by an extremely brief lase

2017 Three most popular high power laser pointers

Many people who like to collect laser pointers prefer high power laser pointers. There are many kinds of high power pointers on the market, and the power of same laser pointer is not same. I through many domestic and foreign forums with my own experience to buy laser pointer, I have sorted out the following several highly praised and affordable high-power laser pointers: 1. Lucklaser's 445nm 5000mW laser pointer  At present, 5W is almost the highest power. L has the actual power of the laser pointer video, as well as outdoor shooting actual light beam effect diagram. This laser pointer can achieve everyone's expectations of 5w. It also has a safety lock device, and a lens 5 different spot pattern. The most important thing is that the price is cheap. 2. Blue 2W laser pointer At first glance you will be attracted by this laser pointer. The blue laser 2000mw is the highest power that enough to light matches,cigarettes,plastics,even at 4 meters away when focus righ

How Are Q-Switched Lasers Used?

A quality-switched laser (Q-Switched ) is a non-invasive laser that creates high-intensity pulsed beam light. The Q-Switched laser beam pulses last a mere billionth of a second. The energy emitted from a Q-switched laser is concentrated into very powerful pulses. Q-Switched lasers are able to shatter tiny fragments of pigmentation or ink, stimulate collagen production or kill fungus. Because their contact with the skin is less than other lasers, Q-Switched lasers are known for not damaging surrounding tissue and causing unwanted side effects. With advanced technology, Q-Switched lasers are used for many conditions, including the following: Tattoo removal Treatment of onychomycosis (toenail fungus) Age spots Sun spots Birthmarks Freckles Moles Spider veins Café-au-lait spots Telangiectasia Angiomas Port wine stains Skin rejuvenation Types of Q-Switched Lasers There are several types of Q-Switched lasers.
