应用染料激光器半经典理论,数值模拟了脉冲染料激光器双频及宽谱共增益区的谱线竞争效应,与实验结果符合较好.在双频相关调谐工作条件下,调谐范围增大近25%.在宽谱工作条件下,随着输出耦合损耗增大,谱线宽度逐渐减小.
The half-classical theory of dye laser is used to numerically simulate the spectral line competition effect of pulsed dye laser in dual-band and wide-band common-gain region, which is in good agreement with the experimental results.Under the condition of dual-frequency tuning, the tuning range increases by nearly 25% Under wideband operating conditions, the spectral width decreases as the output coupling loss increases.
