声光调制正反馈环路的实验研究

Experimental Research on the Positive Feedback Loop for Acousto-optic Modulation

通过研究声光调制器的原理及性能,设计了两种声光调制器的正反馈光学环路。一种环路可以提高声光调制器衍射效率,另一种环路可以实现光学频率梳。

Through the studies on the principles and performances of acoustic-optic modulator,this paper designs two optical loops to achieve the positive feedback of acousto -optic modulator. One of the loops can improve diffraction efficiency of acousto-optic modulator,and other one of the loops can realize the optical frequency comb.
