利用光学阴影探测方法研究了调Q-YAG脉冲激光在生理盐水光学击穿阈值附近诱导微等离子体和冲击波产生的过程,得到了微等离子体和冲击波随人射激光能量和延迟时间而变的系列光学阴影图,并且指出了冲击波的机械作用在脉冲激光眼科医疗中的影响。

Microplasma and shock waves in the physiological saline produced by a Q-switched pulse YAG laser with nearby optical breakdown threshold energy are investigated by using optical shadowing exploring method, and a series of optical shadowgraphs of microplasma and shock waves versus the incident laser energy and the delay time are obtained. Influence of mechanical action of shock waves for the high--POwer pulse laser on the ophthalmic treatment is discussed.
