Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...

Being able to see inside a closed room was a skill once reserved for super heroes. But researchers at the Stanford Computational Imaging Lab have expanded on a technique called non-line-of-sight ...

Although the detailed physics of what goes on inside a laser is typically complex, all conventional lasers share a common basic operational principle: a process known as the stimulated emission of ...

Osram Opto Semiconductors has introduced the first compact laser multi-chip package. The PLPM4 450 module can pack up to 20 blue laser chips into a single "butterfly" package for projection ...

A compact ultraviolet-B (UV-B) semiconductor laser diode emitting at 318 nm under continuous-wave operation at room-temperature. The device demonstrates stable UV-B lasing on a low-cost sapphire ...
