Highly scannable injection seeded nanosecond Ti:sapphire ring laser

L. Cabaret , C. Drag

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 (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.
