We report a novel integrated {ital Q}-switched laser constructed from a bulk domain-inverted single Nd:LiTaO{sub 3} crystal that combines the laser gain and the electro-optic effect. The {ital Q} of the cavity is controlled electro-optically by exploitation of the deflection that occurs at the boundary of two oppositely directed domains under the application of an electric field. The integrated {ital Q}-switching element, with dimensions of 4.1mm{times}4.6mm{times}1mm, generates 22-ns pulses at 1.08{mu}m with a peak power of 64 W and an operating voltage of {similar_to}600 V. The output is seen to be completely free from prelasing or afterpulsing. {copyright} {ital 1995} {ital Optical} {ital Society} {ital of} {ital America}.
