Abstract

When numerically modeling optical extraction from a high energy laser it is necessary to interpolate the loaded gain to determine the gain to be applied to the optical field propagating around the optical resonator. In high gain laser systems direct interpolation of the loaded gain can cause aberrant intensity spiking near the edges of the field because both loaded and unloaded points of the gain distribution will be used to obtain the gain to be applied to the field. A new interpolation method which significantly reduces these intensity artifacts is described and illustrated. The method may be used with both geometric and wave-optic propagation algorithms.
