LETTERS TO THE EDITOR: Flashlamp-pumped Al2O3:Ti3+ crystal laser with acoustooptic control of the emission parameters

Acoustooptic control of the emission parameters and attainment of active mode locking in a flashlamp-pumped Al₂O₃:Ti³⁺ laser are reported for the first time. It is shown that efficient and precise emission wavelength tuning is possible in the range 690-910 nm if an acoustooptic deflector is used. In the case of active mode locking the duration of the output pulses tunable in the range 700-900 nm is less than 1 ns.
