A YAlO/sub 3/:Nd/sup 3 +/ crystal laser with a prism dispersive resonator was constructed. It emitted frequency-tunable radiation corresponding to the /sup 4/F/sub 3//sub ///sub 2/ ..-->.. /sup 4/I/sub 11//sub ///sub 2/ (lambda/sub l/ = 1.0796, 1.0729, and 1.0644 ..mu..) and /sup 4/F/sub 3//sub ///sub 2/ ..-->.. /sup 4/I/sub 13//sub ///sub 2/ (lambda/sub l/ = 1.3413 ..mu..) transitions. When the Q factor was modulated by an electrooptic switch made of an LiNbO/sub 3/ crystal and the lowest transverse mode TEM/sub 00/ was selected, the radiation power at the wavelengths 1.0796, 1.0644, and 1.3413 ..mu.. was approx.7, 3.5, and 0.9 MW for pulse durations approx.14, 25, and 80 nsec, respectively. The values of the gain were determined for a YAlO/sub 3/:Nd/sup 3 +/ crystal in the case of linear lasing resulting in the emission of the 1.0796, 1.0644, and 1.3413 ..mu.. lines.
