Abstract

Passive Q-switching operation has been demonstrated with a class of mixed Nd:Lu(x)Gd(1-x)VO(4) laser crystals. With respect to that obtained with Nd:GdVO(4), the passive Q-switching performance, including threshold, pulse energy, and peak power, was found to be greatly enhanced with the mixed vanadate crystals. The shortest pulse width of 6.2 ns, largest pulse energy of 192.5 microJ, and highest peak power of 31.1 kW were obtained at the incident pump power of 13.75 W with the mixed crystal for x=0.5.

摘要

已通过一类混合的Nd:Lu(x)Gd(1 - x)VO(4)激光晶体实现了被动调Q运转。相对于Nd:GdVO(4)所获得的结果，发现混合钒酸盐晶体的被动调Q性能，包括阈值、脉冲能量和峰值功率，都有了极大提高。对于x = 0.5的混合晶体，在13.75 W的入射泵浦功率下，获得了6.2 ns的最短脉冲宽度、192.5 μJ的最大脉冲能量和31.1 kW的最高峰值功率。
