Paper Abstract

An investigation has been made of improving beam quality of a high power diode pumped solid state rod laser. It was determined that the beam quality is limited by aberrations present in the medium, which may be due to mode-medium effects in the Yb:YAG laser. A diffractive optics propagation model was developed to predict the phase distortions present on the laser wavefront at the resonator mirror. Resonator mirrors were then fabricated with the proper correction applied to correct the distorted wavefront. The beam quality improved from M2 = 2.0 to M2 =1.4.
