Unidirectional operation properties of CW ring dye laser

本文讨论了连续波环形染料激光器的单向运转特性。采用改进的Ganiel速率方程模型,分析了在单向运转条件下泵浦光通量、染料分子密度等参量对激光光通量、激发单重态粒子集居数密度以及增益的影响;揭示了在连续波环形染料激光器中单向运转条件下存在粒子集居数密度的非对称性、激光光通量与激活介质内空间位置的相关性和增益峰值波长的扫描现象。本文给出了数值计算结果。

The unidirectional operation properties of CW ring dye lasers are dicussed. 'Using the improved ganiel model of rate equations, the paper analyses the influences of pumping flux and dye molecules density on photon flux, exeited-sbate population density and gain under condition of unidirectional operation.It points out that there are unsymmetry of population density to the position in the medium and correlation between photon flux and position in the medium, and the wavelength of peak gain has the scanning properties. The numerical computation results are given.
