摘要
报道了几种不同结构的包层抽运调Q光纤激光器。用大功率多模 976nmLD抽运D形内包层掺Yb3 + 光纤 ,对激光器的自调Q ,声光主动调Q ,主被动混合调Q运转状态进行了一系列实验研究。观测分析了调Q光纤激光器的三种阈值情况 ,对它们的输出脉冲特性进行了详细的实验研究。得到了纳秒量级 ,峰值功率～ 2 0 0kW ,重复频率为千赫兹的稳定脉冲序列。
An experimental study of Yb-doped double-clad fiber laser in various optical configurations operating in self-Q-switched, acousto optic modulator (AOM) Q-switched, and hybrid Q-switched conditions is presented. The fiber with a D-shaped inner cladding is pumped by a multi-mode laser diode with high power at 976 nm. Three thresholds of the Q-switched fiber laser are observed and analyzed. And the characteristics of the output pulses are studied experimentally in detail. Pulses with duration of ns, peak power of about 200 kW and the repetition rate of kHz are obtained. The results of the experiment are explained qualitatively.
