Paper Abstract

A planar YAG waveguide with a 200 micrometer Nd doped core, produced by a diffusion bonding process, has been face pumped by an array of qcw laser diode bars, producing 9.3 W of average output power at 8% duty cycle, with 24% conversion efficiency. The multi-pass pumping using a slotted mirror reflective pump chamber has been modeled by a matrix method, accounting for both laser diode temperature tuning effects and the pumping efficiency found in the experiment.
