Paper Abstract

By establishing the model of chemical laser cavity, the eigen mode of laser and the phase distribution of output beam have been simulated numerically, and the influence of inhomogeneous gain on phase characteristics of output beam has been discussed detailedly by analyzing the power spectral density of wavefront phase. The results show that the inhomogeneous gain of chemical laser gives rise to the phase distortion of output wavefront and the obvious increase of high-frequency phase in distortion wavefront; in addition, the degree of high-frequency phase distortion is influenced by the ratio of each component in gain mediums. Therefor, the key factor that resulting in the distortion of high-frequency phase is the inhomogeneous gain.
