Calculation of peak intensity for Yb3+:YAG short pulse from a ring cavity including spectral information

Abstract

On the basis of the spectral information, a theoretical model is developed to calculate the peak intensity of the short pulse from an active continuous wave injected ring cavity with Yb3+:YAG amplifier. Starting from rate equation, the formula describing the short pulse is obtained. As a computable model, it takes into account the pump absorption saturation and the laser reabsorption. By this model, the peak intensities of the short pulse under different cases are analyzed.
