Abstract
A system includes a master oscillator configured to generate a low-power optical beam. The system also includes a planar waveguide (PWG) amplifier having one or more laser diode pump arrays, a planar waveguide, and a light pipe. The one or more laser diode pump arrays are configured to generate pumplight. The planar waveguide is configured to generate a high-power optical beam using the low-power optical beam and the pumplight. The light pipe is configured to substantially homogenize the pumplight and to inject the homogenized pumplight into the planar waveguide. The light pipe is also configured to inject the low-power optical beam into the planar waveguide.
