Mar 2012
A prototype of a high-power 532-nm compact green laser module developed by QD Laser Inc. of Kanagawa, Japan, was displayed at SPIE Photonics West in San Francisco in January. The device, developed with the Institute for Nano Quantum Information Electronics, the University of Tokyo and Fujitsu Laboratories Ltd., has confirmed green light output greater than 100 mW under continuous-wave conditions and high-speed modulation of more than 100 MHz. They also obtained a linewidth of <0.01 nm with a high side-mode suppression ratio. The green laser is suitable for applications including fluorescence microscopy and spectral analysis in the life sciences.

diode-pumped solid-state laser
A compact solid-state laser, referred to as DPSSL, created when a laser diode pumps light into either the sides or end of gain crystal. Depending on where the pumping occurs, high-quality and stable output beams can be achieved with end-pumped lasers, and high-power output beams can be realized as with side-pumped lasers. Common in green laser pointers, DPSSLs are also used for a variety of materials processing applications, such as cutting and precision marking, and in optogenetics.
