Scientists have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements from the fourth group of the periodic table—the "silicon group." The rapid ...

High-power semiconductor laser diodes represent a critical technology underpinning modern industrial, medical, and telecommunications applications. These devices convert electrical energy into ...

In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported a photopumped lasing from a buried dielectric ...

The booming semiconductor industry has led to a surge of emerging Chinese laser manufacturers, yet weaker players are being weeded out based on precision and accuracy as competition intensifies, ...

Scientists from Laser Center Hannover (“LZH”) and Berlin’s Ferdinand-Braun-Institut (FBH) are jointly researching electrically pumped semiconductor disk lasers for ultra-short pulse (USP) generation.

The research team proposed the 'Laser-Induced Leakage Current Mapping' technique, which uses a laser to precisely examine the leakage current distribution within the insulating layer. This method can ...
