摘要

为了实现激光器同孔径下多种波长高功率高频率的可控输出,采用激光放大、高重频调Q、光参量振荡、倍频及扫描反射镜等方法,进行了理论分析和实验验证.取得了在电源电流为42A、调Q频率10kHz的共孔径下,选择性输出40W的0.532μm、100W的1.064μm和12.6W的3.9μm激光的实验数据.结果表明,该激光器实验装置可实现同孔径下多种波长高功率、高频率可控输出.%In order to achieve the laser of high power, high frequency and controllable output with the same aperture, using the method of laser amplifier, high frequency tuning Q, optical parametric oscillator(OPO), frequency doubling and scanning reflection mirror, theoretical analysis and experimental verification were carried out. Selective laser outputs 0. 532μm of 40W, 1. 064μm of 100W, 3. 9μm of 12. 6W were gotten under the condition of power supply current of 42A, Q frequency of 10kHz and the same aperture. The results show that the laser with high power, high frequency, controllable output and the same aperture can be achieved by this experimental device.
