Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing ...

Laser technology as we know it was first realized in 1951 when Charles Townes envisaged the concept of microwave amplification by stimulated emission of radiation (MASER) on a park bench in Washington ...

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." Built from ...

A continuous Bose–Einstein condensate (BEC) has been produced by researchers in the Netherlands. Claimed as a first, the achievement has been sought for years and could lead to continuous-wave atom ...
