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

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

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

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

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.

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
