Low-threshold, multi-gigahertz repetition-rate femtosecond Ti:sapphire laser

A repetition rate of 2.3 GHz is achieved in a femtosecond Ti:sapphire laser. Pulses of 240 fs duration centred on 840 nm are produced from a simple 4-mirror laser cavity that incorporates a saturable Bragg reflector and operates at pump powers as low as 400 mW.
