A novel pump scheme-chamfered-edge-pumping was employed for pumping a planar waveguide laser: A 12 mm-long edge was chamfered as a 0.2 mm wide bevel, pump light from the fast-axis-collimated LD was focused and coupled into the crystal through the chamfered-edge with a pump efficiency of 82%. The sin
