We have carried out a series of experiments on a gain-switched Ti:sapphire laser to investigate the temporal characteristics of the output pulses. In these experiments the minimum laser pulsewidth of shorter than 2 ns has been obtained and pulsewidth can be varied from 5 ns to 27.5 ns continuously under our experimental condition. Using only one output coupler the laser tunable range was greater than 2.1 X 103 cm-1 (from 720 nm to 850 nm). A maximum output pulse energy of 4.65 mJ at 780 nm was obtained. The spectral content of the output from the laser with three intracavity prisms was less than 0.14 nm (FWHM).
