Abstract
A compact high-power planar waveguide laser end pumped by a diode-bar is reported. The waveguide was fabricated by liquid-phase epitaxy and had an 80-mu m-thick, 1.5-at. % Nd:Y(3)Al(5)O(12 )core on a Y3Al5O12 s ubstrate. A maximum output power of 6.2 W was obtained at 1.064 mu m w hen the device was pumped with a 20-W diode bar operating near 807 nm, giving an overall optical-to-optical conversion efficiency of 31%. Th e total device length was 5 cm. (C) 1998 Optical Society of America.
