We report single-transverse-mode laser oscillation from waveguides inscribed in a commercially available Nd-doped silicate glass substrate using an ultrafast fiber laser operating at 1064 nm. When pumped at 808 nm, laser action was observed at 1062 nm, with a slope efficiency of 15.0% and a maximum output power of 7.5 mW. Analysis of the laser performance implied a waveguide loss of 0.17±0.06 dB.cm.-1 © 2006 IEEE.
