非激光振转能级对CO2激光器小信号调制响应的影响
Effect of non-Iasing vibro-rotational levels on the response of small signal modulation for a CO2laser
摘要
本文以简化的多能级理论模型为出发点,讨论了具有均匀加宽介质的单模CO2激光器的稳态特性,线性稳定性和小信号腔长调制响应,泵浦调制响应,增益或损耗调制响应,并将其结果与由简单的二能级理论所得的结果进行比较,着重分析了非激光振转能级对上述三种调制响应的影响.
Abstract
In this paper, the steady state behaviour, linear stability and the response to small signal modulations of cavity length, pump and gain or loss of a sigle mode CO2 laser with homogeneously broadening medieum are analysed based on the vibro-rotational model. The results are comparaed with the similar analysis for two-level rate-equation model. We put special emphasis on the effect of the non-lising Vibro-rotation levels on the response of the three modulations mentioned above.
