【Abstract】 In this paper, a model program has been established to investigate the amplified spontaneous emission (ASE) in the Nd:glass disk amplifier with the Monte Carlo method and rays tracing. The distribution of ASE loading on the edge of a disk is firstly calculated. The effect of disk aspect radio on ASE gain reduction is also investigated. Allowance is made for the effect of different reflectivity under the condition of different incidence on two faces.更多还原
