用压电陶瓷作反馈的光学双稳态

Bistable Optical Devices by Using Piezoelectrical Ceramic for Feedback

光学双稳态需由一个反馈函数和一个调制函数所组成。本文指出可以用压电陶瓷做光电反馈函数,用法——白干涉仪做光调制函数来组成光学双稳装置。本文给予了理论证明,并作出了实验装置和实现结果。文中还报导了把这种装置用于稳定He-Ne激光器的输出光强,取得了很好的实验桔果,并指出了该装置的实用价值。

A bistable optical device must be constituted by a feedback function and a modulating function.This paper proved that we could get feedack function by using piezoelectrical ceramic,and modulating function by using Fabry-Perot interferometer.The paper proved these on theory,and presented the experimental devices and results. By using this device to stabilize the He-Ne laser output power,we got a good experimental result.Finally,the practical value is discussed in this paper.
