Abstract

We report on the design and fabrication of Nd:YAG planar waveguides suitable for in-plane, diode-bar pumping. Contact-bonded Nd:YAG on Sapphire waveguides are shown to have the high numerical aperture (0.46), low propagation loss (<0.2dB/cm), and good thermal properties necessary to make efficient diode-bar-pumped lasers and amplifiers. Coupling efficiencies of 73% and 60% have been demonstrated between a 20W diode-bar and an 8µm and a 4µm thick planar waveguide respectively, leading to 3.7W of waveguide-laser output.
