摘要
目的:提出利用光栅光阀(GLV)来精密调节光栅外腔半导体激光器输出波束的新方法。方法:这种基于光栅光阀的可调谐外腔半导体激光器的结构使光栅光阀与闪耀光栅形成了共焦结构,便于使被选择的波束可以原路返回,经过在谐振腔中振荡,最后输出。结果:这种基于光栅光阀结构的可调谐外腔半导体激光器可以任意控制输出或者被过滤掉的相应波束的数量。结论:利用光栅光阀的特性,这种可调谐外腔半导体激光器能有效地实现激光输出波束的精密调谐,同时也降低了调谐的机械难度。
Objective： It presents a new method that makes use of Grating Light Valve（ GLV）in oilier to adjust minutely output wave - packet in grating external cavity semiconductor laser. Methods：This structure in tunable semiconductor laser based on grating light valve forms grating fight valve and blazed grating into confocal structure, wave - packet selected can backtrack and be exported in the end by oseillating movement in resonant cavity. Resuhs： The tunable external cavity semiconductor laser based on grating light valve can select at will output or fihrated corresponding wave - packet magnitude. Conclusion ： This kind of tunable external cavity semiconductor laser using characteristic of grating fight valve can achieve minutely tuning of output wave - packet and reduce mechanical tuning difficulty.
