A semiconductor laser that emits light in the 400-450 nm range. Although it was very difficult developing blue lasers, which emit smaller wavelengths than other colors, blue lasers became ...

The development of new blue semiconductor laser devices in Japan is building on an expertise in gallium-nitride semiconductor-based optical devices, used for LEDs. By tweaking the crystal layers ...

founded Blue Laser Fusion in Palo Alto, California, in November. Partners include Hiroaki Ohta, a former CEO of drone maker ACSL Ltd. The start-up, which raised $25 million (about 3.5 billion yen ...

The reed mechanism was a breakthrough in high-precision measurement and is still used today for sub-micron or even nanometer resolution applications.

Whereas five years ago a 488-nm blue laser was considered state-of-the-art, today's fabrication plants require UV sources for inspection. According to Schulze, there's a push to shorter ...
