The beam quality and the system efficiency of a diode-pumped solid-state laser source are directly
related to the thermal profile inside the laser crystal. The thermal profile in a laser crystal should be
made uniform in order to reduce the negative effects of the thermal lens. However, the absorbed pump
profile that forms a uniform thermal profile inside the gain medium may adversely affect the system
efficiency. In this thesis, a computational and empirical method was developed for designing pumping
chambers that results in a suitable thermal profile inside the gain medium, and thus desired laser beam
quality was achieved while keeping the system efficiency at an acceptable level. Accomplishment of
this thesis work will lead to the design of pumping chambers and resonators in high power laser
systems operating at even higher thermal loads.
