• The steady-state 3D numerical model of parasitic amplified spontaneous emission (ASE) in the active element of a high-power neodymium laser has been developed. Within the proposed model the numerical calculations of spontaneous emission transfer through the neodymium slab with amplification have been made, which allows us to determine the decreasing of the gain coefficient at slab's edges. Calculated results agree with the results of experimental measurements of the gain coefficient.
