Abstract :
It presents a new method that makes use of grating light valve (GLV) in order to adjust minutely output wave-packet in grating external-cavity semiconductor laser. This structure in tunable semiconductor laser based on grating light valve forms grating light valve and blazed grating into confocal structure, Wave-packet selected can backtrack and be exported in the end by oscillating movement in resonant cavity. The tunable external-cavity semiconductor laser based on grating light valve can select at will output or filtrated corresponding wave-packet magnitude. This kind of tunable external-cavity semiconductor laser using characteristic of grating light valve can achieve minutely tuning of output wave-packet and reduce mechanical tuning difficulty.
