Paper Abstract

The practical aspects of measuring and defining the beam parameter products of laser beams from high-average-power solid state lasers with unstable resonators are presented. In particular, measurements at kW-class Nd:YAG slab laser are discussed. Emphasis is on experimental techniques, measurement errors, and the influence of thermo-optical aberrations. Numerical Kirchhoff-integral calculations of the unstable resonator modes of a slab laser with thermo-optical aberrations are presented and discussed.
