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. The crystal rods inside the lasers differentia

Laser pointer also has a use you do not know

Have you ever tried to kill mosquitoes with laser pointer? I'm sure many people even don't know what a small laser pointer can do it. Really you can kill pests with an ordinary laser flashlight? Can you drive crows? Today we use a 3W Blue laser pointer to test the insects on the tree. Let's see it. www.lucklaser.com

Application of fiber lasers in different industries

Fiber lasers are gradually replacingtraditional lasers in laser marking, laser welding, laser cutting and other areas of dominant position.Today to explain the fiber laser in the field of advantage. Application of fiber laser marker in industry Industrial production requires high reliability, small size, quiet and easy to control. Fiber laser with its compact layout, light conversion to high, short preheating time, influence factors, maintenance free and easy and small fiber or by optical lenses composed of light guide system coupling strengths favored by people. Fiber lasers are gradually replacing traditional lasers in laser marking, laser welding, laser cutting and other areas of dominant position. In the marking field, because of the high beam quality and positioning precision of fiber laser, fiber marking system is replacing Nd:YAG laser pulse marking system which is not obeyed by CO2 laser and xenon lamp.In Europe and Japan, for the big range hold, only in Japan,

Infrared workshop in Arizona to connect mid-IR research and industry

Source: http://www.laserfocusworld.com A workshop dedicated to IR technology aims to focus on new developments related to detectors for commercial instrumentation, sources and filters, instrument subsystems, and commercial applications. The 4th International WORKshop on Infrared Technologies, held for the first time in the U.S., will take place at Arizona State University in Tempe, on November 8–9, 2017.  The workshop is a collaboration of Laser Components, MIRTHE+ Photonics Sensing Center at Princeton University, and the Center for Photonics Innovation at Arizona State University. Specific topics include fiber-coupled interband cascade lasers, InAsSbBi/GaAsSbBi heterostructures, operating temperature improvements for nBn detectors, laser-based trace gas sensing, and novel spectroscopy techniques. Industry speakers are part of the program since the goal is to create a community conversation about industry challenges and breakthroughs, to generate professional connections and co
