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 ...
Usually, these advanced devices require large, costly ultrashort-pulse lasers as excitation sources. However, realizing a practical far-ultraviolet light source requires a blue semiconductor laser ...
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 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 ...
The reed mechanism was a breakthrough in high-precision measurement and is still used today for sub-micron or even nanometer resolution applications.
