Abstract

A theoretical and experimental study investigated beam perturbations on propagation through a MOPA chain, including both optical and medium influences. Analytical models are presented to explain the influence of thermal aberrations on the beam, and these effects are related directly to the change in M2 (quality factor) of the beam.
