The resulting laser is reported to preserve single-mode lasing even at very high gains. While the first discovered topological insulators were electronic, nowadays scientists have developed them in ...

Chen notes that this vertically oriented "rainbow-like" or "arc-like" lasing mode reflects back and forth between the two ends of the droplet interface, forming a unique and extremely strong laser ...

Laser-cooled atomic gases, gases of atoms chilled to temperatures around absolute zero using laser technologies, have proved to be versatile physical platforms to study and control quantum phenomena.

Lasing, light amplification by stimulated emission of radiation, is a key attribute for many important applications in optical communications, medicine and defence. Conversely, anti-lasing ...

Besides, abundant secondary radiations, e.g., supercontinuum white light, air lasing, fluorescence, provide natural probe sources for atmospheric detection at a remote location. Particularly ...

Researchers successfully conducted a room-temperature continuous-wave lasing of a deep-ultraviolet laser diode (wavelengths down to the UV-C region). A research group led by 2014 Nobel laureate ...

So, we excluded different possibilities step by step until we finally started to understand what was going on and found out that without us even trying, this lasing mechanism stabilizes the ...
