【摘要】 成功研制了一台高功率二极管泵浦声光Q开关腔内倍频Nd:YAG激光器。当泵浦功率约为350W时,采用透过率为30%的输出耦合镜,调Q激光输出功率32.5W,脉宽约200ns,重复频率7kHz;采用Ⅱ类匹配KTP晶体腔内倍频,获得了32.5W的绿光输出,脉宽约120ns。输出光束平滑,远场为类高斯分布,测得的光束质量因子为3.6。更多还原

【Abstract】 A high power diodepumped Qswitched intracavitydoubled Nd:YAG laser has been developed successfully. A Qswitched laser output of 32.5W with 350W pumping power is obtained at 7kHz using a 30% output coupler. A green output of 32.5W is achieved with pulse duration of about 120ns using a type II KTP crystal. The output beam exibits a smooth Gaussianlike profile in the far field and the beam quality factor is measured to be 3.6?更多还原
