摘要

In this paper, a model of a Cr:ZnSe laser amplifier at a wavelength of 2.4 μm is described. The effects of gain saturation and pump depletion in the gain medium are considered at different concentrations of active centers and the amplifier lengths. The effect of non-uniform distribution of Cr2+ ions on the overall gain and the cross-section intensity distribution of the signal beam is estimated.
