摘要
报道了LD侧面抽运Nd∶YVO4 532 nm准连续绿光激光器。为了获得高功率的532 nm绿光输出,通过采用声光调Q技术和LD侧面抽运Nd∶YVO4技术来获得高功率线偏振的1064 nm激光输出。采用Ⅰ类相位匹配三硼酸锂(LBO)晶体腔内倍频,实现高功率532 nm激光输出。在电源输出电流为30 A、声光调Q的调制频率为20 kHz的工作条件下,获得平均输出功率为33 W的线偏振1064 nm基频光,通过LBO晶体倍频获得平均输出功率为23.5 W的532 nm绿光。1064 nm基频光到532 nm绿光的光-光转换效率达71.2%,脉冲宽度为44.3 ns,偏振比为254∶1。
Abstract
The LD side-pumped Nd∶YVO4 532 nm quasi-continuous green laser is reported. The acousto-optic Q-switched operation and the laser diode side-pumped Nd∶YVO4 laser are used to get high-power linearly polarized 1064 nm laser output. High-power 532 nm green laser output is achieved by typeⅠphase-matched LiB3O5 (LBO) as second harmonic generation crystal. An average output power of 23.5 W at 532 nm is obtained under the condition of input current of 30 A, the repetition rate of 20 kHz and the 1064 nm fundamental wave of 33 W. The optical-optical conversion efficiency is up to 71.2%. The pulse width is 44.3 ns and the polarization ratio is 254∶1.
