Abstract
A laser with a quasi-top-hat pump beam has a modified intensity profile that produces a parabolic temperature gradient. The laser includes a high reflector and an output coupler defining a laser cavity. A gain medium positioned in the laser cavity. A first diode pump source produces a first pump source beam. An intensity profile of the first diode pump source beam is tailored to produce the parabolic temperature gradient across the gain medium.
