Abstract
Many solid-state laser applications require both high intensity and low divergence or, simply, high brightness. End-pumped lasers can provide this through excellent beam quality and very high conversion efficiencies. Pump source arrangements have been used in which the power from many lasers is concentrated in the active medium to increase output power. Non-uniform heating of the active material in these lasers produces higher order spherical aberration. We have analyzed tire effects of aberration on the performance of end-pumped lasers designed for fundamental mode operation as a function of material properties, resonator parameters, and pump geometry.
