Abstract
We report the use of a 5-mm-long planar Nd:yttrium aluminum garnet waveguide grown by liquid-phase epitaxy as an amplifier at 1.064 μm. In a double-pass configuration pumped by a 1.2 W diode laser, small signal gains of 686 (28 dB) have been observed and efficient power extraction demonstrated with output powers of up to 290 mW being obtained.Keywords
