英文摘要	amplified spontaneous emission (ase) causes the decrease of the inverted population density adn the nonuniformity of gain in slab amplifier for high power laser systems. in this paper, a three dimension model, based on the data in sg-ii, in which the residual reflection in the cladding and the ase process are taken into consideration, is built to analyze the space distribution and time evolution of small signal gain coefficient using monte carlo algorithm and ray tracing. this model has been verified by comparing with the experimental data. the traverse size of slab is 68.2cmx36.3cm, which is usually decided by the clear aperture and the manufacture. by means of the model, the impact of thickness, residual reflectivity and the stimulated cross section of neodymium glass to the ase are analyzed in detail.
