A widely tunable injection seeded Ti:sapphire ring cavity has been developed and characterized. The seeding source is a single mode quasi continuous wave Ti:Sa laser, continually tunable over more than 2.5 cm-1 (75 GHz). Its short term (pulse to pulse) stability is on the order of ±3.2 MHz at a repetition rate of 20 Hz. The long term absolute stability is limited up to now to about ±10 MHz. These frequency characteristics are transferred to the pulsed emission with minor degradations. The frequency chirps and shifts during the pulses are also studied using an optical heterodyne technique.
