Continuous-wave integrated-optic channel waveguide lasers operating near 1.06 μm have been fabricated by thermal silver ion exchange in a commercial neodymium-doped glass. The laser slope efficiency and threshold as a function of waveguide width are measured. The laser output wavelength is also shown to display a dependence on the waveguide width. Optimum laser condition is obtained for waveguide structures with 7.5 μm widths.
