We report the first operation of a side-pumped crystal waveguide laser. Both diode array and dye laser side-pumping of an epitaxially grown Nd:YAG planar waveguide laser have been demonstrated, with thresholds as low as 8 mW observed for a simple plane mirror cavity. Output slope efficiencies of 19% have also been demonstrated. The threshold and slope efficiency of this system is found to be in good agreement with a simple analytical model.
