Solid-state and gas lasers have followed largely divergent development paths. Gas lasers are based primarily on direct electrical discharge for pumping (energizing), while solid-state lasers are ...

A diode is an electric device which allows the flow of current only in one direction and restricts the current flow in the opposite direction. A diode starts its operations when a voltage signal is ...

The most efficient diode ever made using carbon nanotubes has been unveiled, marking another step towards practical atomic electronics. Carbon nanotubes – structures resembling rolled up cages made ...

The 2014 Nobel Physics Prize was presented to three researchers, Professor Isamu Akasaki, Professor Hiroshi Amano and Professor Shuji Nakamura for the invention of an efficient blue light-emitting ...

The new extra fast soft recovery diodes are diodes capable of operating at high commutation rates. It has low reverse recovery current and is outstanding in their dynamic characteristics. In this ...

As part of a NEDO project, Osaka University and Shimadzu Corporation have developed two new types of RGB laser light source modules, including a world-class high-brightness model and an ...
