摘要
分析了Nd:YVO4激光器实现双波长运转及腔内和频的条件, 利用一种LD泵浦Nd:YVO4晶体产生1 064 nm和914 nm双波长激光束,采用一个线性平凹腔结构, 利用腔内Ⅰ类临界相位匹配LBO和频, 获得了连续波输出的全固态激光器。实验采用端面结构, 在5.0 W的808 nm泵浦功率下, 获得了最高功率为25 mW连续波TEM00的激光输出, 光-光转换效率为0.05%。
Abstract
The oscillation condition for the simultaneous dual-wavelength operation and intracavity sum-frequency mixing in a diode-end-pumped Nd:YVO4 solid-state laser is analyzed. A CW laser at 491 nm is reported with an LD-pumped Nd:YVO4 crystal and a type I critical phase matching LBO as the laser crystal and the intracavity sum-frequency mixing crystal, respectively. By the simple linear resonator, TEM00 mode laser at 491 nm of 2.5 mW was obtained with 5.0 W injection pump power. The optical-to-optical conversion efficiency was 0.05%.
