We present a numerical model for the transient response of a longitudinally pumped miniature solid-state laser. The model is suitable for both regenerative amplifiers and oscillators, provided the latter run in a single mode. The results of our calculations compare well with measurements of the peak output powers and pulse widths for a Nd:YAG rod pumped by a ten-stripe diode laser array. Our model predicts saturation at peak powers of approximately twice the 850 mW reported here due to filling of the lower laser level. To overcome this power limitation due to saturation, we also explore the use of miniature Nd:glass laser amplifiers to boost the single-frequency Nd:YAG pulses to powers exceeding 200 W.
我们提出了一种用于纵向泵浦微型固态激光器瞬态响应的数值模型。该模型适用于再生放大器和振荡器，前提是后者以单模运行。我们的计算结果与由十条纹二极管激光阵列泵浦的Nd:YAG棒的峰值输出功率和脉冲宽度的测量结果吻合良好。我们的模型预测，由于较低激光能级的填充，峰值功率将在约为此处报告的850 mW的两倍时出现饱和。为了克服由于饱和导致的功率限制，我们还探索了使用微型Nd:玻璃激光放大器将单频Nd:YAG脉冲的功率提升至超过200 W。
