Growth and low-threshold laser oscillation of an epitaxially grown Nd:YAG waveguide

By S.J. Field, D.C. Hanna, A.C. Large, D.P. Shepherd, A.C. Tropper, I. Chartier, B. Ferrand and D. Pelenc


We report 1064-µm laser operation of an epitaxially grown Nd:YAG planar waveguide with thresholds as low as ~0.7 mW when high-reflectivity mirrors are used. The output is single mode and, when a 83% reflectivity output coupler is used. has a diode pumped slope efficiency of ~40% Output powers in excess of 60 mW have been obtained when pumping with a Rhodamine 6G dye laser
