Experimental Study on Passively Q-Switched Laser with Yb:GdCOB Crystal
摘要
以Cr4+:YAG晶体作为可饱和吸收体，利用平凹谐振腔实现了Yb:GdCOB晶体的被动调Q激光运转。当沿X轴切割的厚度为2.0 mm的晶体吸收抽运功率为6.3 W时，所产生的沿Z主轴方向偏振的平均脉冲输出功率达到0.62 W，脉冲重复率为3.6 kHz，相应的单脉冲能量、脉冲宽度和峰值功率分别为172 μJ、20 ns和8.6 kW。
Abstract
Passively Q-switched laser operation with Yb:GdCOB crystal is demonstrated in a plano-concave resonator, utilizing a Cr4+:YAG saturable absorber. When the absorbed pump power of the 2-mm thick X-cut crystal is 6.3 W, an average pulsed output power of 0.62 W, with polarization parallel to the Z principal axis, is generated at a pulse repetition frequency of 3.6 kHz. The resulting pulse energy, duration, and peak power are 172 μJ, 20 ns, and 8.6 kW, respectively.
