摘要
采用预电离脉冲群开关技术 ,在一具有独特电极结构的横流CO2 激光器上实现了高功率脉冲激光输出。详细介绍了从预电离到主放电 ,最终到激光输出的整个过程中 ,对电压、电流波形及光波形各参数的测量方法 ,并进行了简要分析 ;提出一种利用光的偏振特性对光进行衰减 ,测量光的方法。
The output of a high-power pulsed CO2 laser has been produced from a transverse-flow CO2 laser which has particular electrode structure and using the pre-ionized pulse-train switched technique. The measurement on the voltage wave, current wave and light wave has been introduced in detail, during from pre-ionization to main discharge and finally, to laser output, and the results of the waves have been analyzed in brief. Moreover, a way of light measurement has been put forward by means of attenuating the light which is based on the light polarization feature.
