A passively {ital Q}-switched waveguide laser operating at 1.054 {mu}m has been demonstrated in a Nd-doped phosphate glass. The channel waveguide was fabricated by K-ion exchange from a nitrate melt. Passively {ital Q}-switched pulses were achieved by placement of an acetate sheet containing an organic saturable-absorbing dye within the laser cavity. The resulting pulse train consisted of pulses with a FWHM of {similar_to} 25 ns and peak powers of 3.04 W. With an 80% transmitting output coupler, cw operation of the laser provided 5.2 mW of output power at 1.054 {mu}m for 229 mW of absorbed 794-nm pump power.
