A single-transverse-mode erbium-doped glass waveguide laser operating at a wavelength of 1.53µm is described. The erbium-doped GeO2-SiO2 core of the waveguide was made by electron-beam vapour deposition and patterned by reactive ion etching on a quartz glass substrate. The core was 10µm wide, 8µm high and 64.5 mm long, which permitted single-transverse-mode laser oscillation. The threshold pump power for CW oscillation was 150 ~ 200 mW at a pumping wavelength of 0.98 µm.
