This increased optical power output enables higher measurement precision and accelerated processing of biological samples, ...

Silanna claims the first laser driver ICs to integrate charging and firing on a single chip, enabling smaller, more powerful ...

The US has a new, most powerful laser, creating more than 100 times the ... is still plenty of science that could be done with a 1 petawatt laser. So far, it has welcomed 11 separate experiments ...

Research and development on III-nitride semiconductors gained momentum much later than other conventional semiconductors such as silicon and gallium arsenide. This was due to the difficulty in ...

a liquid crystal on silicon (LCOS)-based spatial light modulator engineered to withstand 1kW-class laser power in the near-infrared spectrum (1-micrometer band). Designed for advanced industrial ...

Abstract: We discuss various mechanisms of laser diode degradation based on our own experiments and on the available literature data. In most of the cases, degradation of InGaN laser diodes occurs ...

Abstract: Significant improvement in the performance of AlGaInP/AlGaAs visible vertical-cavity surface-emitting laser diodes has been achieved in gain ... Threshold currents as low as 1.25 mA were ...
