本文提出了一种分析无腔脉冲固体激光器脉冲特性的理论模型（无腔脉冲固体激光器理论）。采用高增益Nd：YVO_4端面泵浦无腔激光器系统对理论模型进行了验证。结果表明，当小信号增益达到饱和时，无腔结构的输出能量和脉宽性能优于谐振腔结构。理论模型的计算结果与实验结果吻合较好。这一结果证明了理论模型的正确性，对高增益脉冲激光的理论分析具有重要意义。
We propose a theoretical model (cavityless pulsed solid-state-laser theory) to analyze the pulse characteristics of cavity-less solid-state lasers. A high gain Nd:YVO_4 end-pumped cavityless laser system is adopted to verify the theoretical model. It shows that the performance of output energy and pulse width achieved in cavityless configuration is better than that in resonator configuration when the small-signal gain reaches the saturated level. The simulation results calculated by our theoretical model agree very well with the experimental results. This agreement proves the validity of our theoretical model, which has great importance for theoretical analyses of high gain pulsed laser.
