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-µm-thick, 1.5-at. % Nd:Y3Al5O12 core on a Y3Al5O12 substrate. A maximum output power of 6.2 W was obtained at 1.064 µm when the device was pumped with a 20-W diode bar operating near 807 nm, giving an overall optical-to-optical conversion efficiency of 31%. The total device length was 5 cm.
