Semiconductor lasers are small solid-state lasers that use a semiconductor as an active medium to amplify light through stimulated emission at inter-band transitions under high electron density in the ...

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 ...

Uviquity, a deep-tech company developing integrated photonics for ultraviolet wavelengths, today announced its first product: ...

Researchers have developed a chip-scale laser source that enhances the performance of semiconductor lasers while enabling the generation of shorter wavelengths. This pioneering work represents a ...

Chaotic dynamics in semiconductor lasers arise from the inherent nonlinear interactions within the laser cavity, often enhanced by optical feedback mechanisms. These irregular, complex oscillations ...

Ultraviolet (UV) rays are electromagnetic waves with wavelengths ranging from 100 to 380 nanometers (nm). These wavelengths can be classified into three regions: UV-A (315–380 nm), UV-B (280–315 nm), ...

A new galvanometer-based laser processing system reported in Engineering integrates full-in-situ imaging and machining without requiring coordinate conversion or calibration, offering a streamlined ...

Glasgow University spinout Vector Photonics, which has developed photonic crystal surface emitting semiconductor lasers (PCSEL lasers), is poised to commercialize its proprietary PCSEL technology, ...

A team used an infrared laser to cool a solid semiconductor by at least 20 degrees C, or 36 F, below room temperature. To the general public, lasers heat objects. And generally, that would be correct.

Welcome to the laser photonics industry, one of the most important and underappreciated ways to invest in the artificial intelligence technology boom. While semiconductor giants tend to grab headlines ...
