When laser beams propagate through media with non-vanishing absorption, the media is heated resulting in a change of the refractive index, which can lead to thermal lensing and thermal blooming.

With the explosive growth of data traffic, it is highly desired to develop hybrid photonic integrated circuits combining various optical components on a single chip. Silicon is an outstanding material ...

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 ...

Direct Laser Metal Deposition (DLMD), as a Directed Energy Deposition (DED) technique, can operate either continuous-wave (CW) or pulsed-wave (PW) laser emission, resulting in distinctly different ...

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 ...

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 ...

Chinese research team achieved a major breakthrough in continuous-wave vacuum ultraviolet (VUV) light sources, a longstanding bottleneck in the development of the nuclear clock, Science and Technology ...
