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.

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 ...

A compact ultraviolet-B (UV-B) semiconductor laser diode emitting at 318 nm under continuous-wave operation at room-temperature. The device demonstrates stable UV-B lasing on a low-cost sapphire ...

A crucial step towards electrically excited lasing has been made with perovskite lasers in the development of continuous-wave excited lasing from femtosecond pulse excited lasing. Establishing ...

Development led by 2014 Nobel laureate Hiroshi Amano at Institute of Materials & Systems for Sustainability. Nagoya group achieved room-temperature CW lasing of a deep-UV laser diode. A research group ...

The team's experimental setup: Atoms are cooled and slowed inside a vacuum chamber, until they can be trapped in a lattice inside a cavity (black triangular cavity spacer in the bottom half of the ...
