Abstract
A system includes a laser system having a master oscillator and a planar waveguide (PWG) amplifier having one or more laser diode pump arrays, a PWG pumphead, input optics, and output optics. The PWG pumphead is configured to receive a low-power optical beam from the master oscillator and generate a high-power optical beam. The PWG pumphead includes a laser gain medium, a cartridge, and a pumphead housing. The cartridge is configured to receive and retain the laser gain medium, and the cartridge includes one or more cooling channels configured to transport coolant in order to cool the laser gain medium. The pumphead housing is configured to receive and retain the cartridge, where the cartridge is removable from the housing.
