We report on the temporal characteristics of output pulses of a gain-switched Ti3+:A12O3 laser pumped by a frequency-doubled Q-switched Nd:YAG laser. The minimum laser pulsewidth of 1.2 ns has been observed. The pulsewidth can be varied from 5 ns to 27.5 ns continuously under certain experimental conditions. Using only one output coupler the tuning range of the laser was from 730 nm to 850 nm. The maximum output pulse energy of 4.7 mJ and the spectral content of 0.13 nm (FWHM) at 780 nm prisms were obtained, by using three intracavity prisms.
