利用热自散焦实现的激光限幅

Optical limiting by using thermal self defocusing

本文详细研究了利用热自散焦效应实现的对连续激光的光限幅。给出了一个描述限幅器输出功率特性的解析表达式,实验和理论计算较好地符合。

Optical limiting of CW lasers by utlizing thermal self-defocusing has been studied in detail. Analystic formula that describe the relations between input and output power of the limiter are given. Experimental results are in good consistence with theoretical simulations.
