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 ...

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 ...

Over the last 30 years, group-IV semiconductors have been intensely investigated in the quest for a fundamental direct bandgap semiconductor that could yield the last missing piece of the Si Photonics ...

Microscale lasers efficiently deliver coherent photons into small volumes for intracellular biosensors and all-photonic microprocessors. Such technologies have given rise to a compelling pursuit of ...

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 ...

Imagine a symphony that never stops. The musicians are atoms, the concert hall that lets their sound build is an optical cavity, and the skilled conductor is a new continuous loading with strong ...

Our research group is on the quest for the holy grail: an active superradiant atomic clock. Such clocks are so desirable for both practical and scientific reasons, and have the potential to push the ...

A research group led by 2014 Nobel laureate Hiroshi Amano at Nagoya University's Institute of Materials and Systems for Sustainability (IMaSS) in central Japan, in collaboration with Asahi Kasei ...

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 ...
