In the experiment,1.064μm fundamental lighting with high peak power is a-chieved by using electro-optic modulation Q and flashlamp pumpe.1.57μm eye-safety la-ser is achieved with the help of Ⅱ-class noncritical phase matching KTP crystal and Unsta-ble resonator OPO technology.When the radius of mirror curvature is 2m,the characteristics of the output laser with different transmissivity are masured and analyzed in the unstable re-sonator.The laser output of the eye safe band with maximum output energy of 35mJ and pulse width of 1.5ns is obtained.%实验采用电光调Q、闪光灯泵浦实现高峰值功率的1.064μm基频光输出,利用Ⅱ类非临界相位匹配KTP晶体和非稳定谐振腔光参量振荡器Optical Parametric Oscilla-tor(OPO)技术,实现了1.57μm人眼安全波段激光.在腔镜曲率半径为2m条件下,测量分析了非稳定谐振腔OPO中不同透过率输出镜时的激光输出特性,获得了最大输出能量35mJ、脉冲宽度1.5ns的人眼安全波段的脉冲激光输出.
