A new undergraduate degree program in Photonic Science and Engineering started in the fall of 2013 at the University of Central Florida. It is the State of Florida’s only such program, and one of only a few in the nation. Photonics plays a huge role in the Florida’s economy, with over 270 photonics companies employing […]

Imaging at One Trillion Frames per Second
By Ramesh Raskar and Christopher Barsi High-speed imaging is a long-standing goal in optics, with applications in spectral dynamics, motion analysis, and three-dimensional imaging. Currently, commercially available systems can offer sensors operating at one million frames per second at reduced spatial resolution.1 In the lab setting, serial time-encoding of 2D images have provided 100 ps […]
ICALEO 2013 Offers Achievable New Horizons for Laser Industry
By Geoff Giordano Much like the laser-assisted femto photography that has allowed MIT researchers to see around corners, the 32nd International Congress on Applications of Lasers & Electro-Optics (ICALEO®) illuminated photonic research in everything from routine processing to more arcane applications like laser-assisted generation of human cells. And, as did plenary speaker Boris Chichkov with […]
LPP-EUV Light Source Development for High Volume Manufacturing Lithography
By Hakaru Mizoguchi, Junichi Fujimoto and Takashi Saitou EUV Source System We have developed a prototype of the first HVM EUV light source having 100 kHz 20 kW CO2 laser, 20 mm in diameter droplet generator, and magnetic field debris mitigation (Fig. 1).
Origin and New Wave of Laser Welding
By Isamu Miyamoto The author started laser materials processing in 1965 with developing the CO2 laser, and since then has been involved in a variety of materials processing using CW (continuous wave) to USLP (ultrashort laser pulse). Among them laser welding has attracted a lot of the author’s interest because of its profound and interesting […]
