This study explores the development of Group-IV semiconductor lasers for cryogenic applications, demonstrating ...

Scientists have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements ...

High efficiency and broad wavelength coverage can be obtained by using an Optical Parametric Oscillator (OPO) for the down-conversion process. When pumped with a single-frequency continuous-wave (CW) ...

These include the linear frequency modulated (LFM) waveform central to frequency modulated continuous wave (FMCW) radars and chirp pulse radars. We also studied an antitank missile, which uses ...
