We report the 946nm laser operation of an epitaxially grown Nd:YAG planar waveguide. The incident and absorbed power thresholds of 4mW and 1.2mW respectively are lower than those reported for bulk lasers when using a similar experimental set up. We also report the use of Ga doping of the active layer to increase the refractive index difference to allow the production of very small guiding layers.

Abstract

We report the 946nm laser operation of an epitaxially grown Nd:YAG planar waveguide. The incident and absorbed power thresholds of 4mW and 1.2mW respectively are lower than those reported for bulk lasers when using a similar experimental set up. We also report the use of Ga doping of the active layer to increase the refractive index difference to allow the production of very small guiding layers.
