A demonstration of a planar waveguide laser configuration for single-mode operation around 1550 nm using cost-effective multimode diode pumping was reported. The laser was fabricated by Ag film ion exchange in a hybrid phosphate glass. A single transverse mode waveguide laser output power of 54 mW was measured. It was anticipated that the laser performance could be greatly improved by optimizing the cavity and the waveguide index profile.
