Regeneratively-initiated, self-sustained, continuous-wave mode-locked operation of a chromium-doped forsterite laser operated at 3.5[degree]C is described. Without compensating for the positive group velocity dispersion of the cavity, regenerative, acousto-optic modulation produced pulses of between 41 and 6.5 psec (FWHM) at 1.23 [mu]m with average output powers of between 280 and 380 mill, respectively. By employing intracavity negative group velocity dispersion compensation, nearly transform-limited femtosecond pulses of 48 fsec (FWHM) duration were generated with average TEM00 output powers of 380 mW at 1.23 gm. These represent the shortest and highest peak power pulses directly generated from this laser system to date.
