2-DIMENSIONAL SIMULATION OF A HIGH-GAIN, GENERALIZED SELF-FILTERING, UNSTABLE RESONATOR

The performance of a high-power excimer laser, generalized self-filter ing, unstable resonator has been modeled by means of a numerical code. The spectral method and the Rigrod equations are basic to the numeric al procedure, which is quite general because it results from an approp riate combination of independent propagation algorithms. The code can be applied to arbitrary resonator geometry and can be used to take acc ount of gain medium inhomogeneities and instability phenomena. (C) 199 7 Optical Society of America.
