Abstract

We have demonstrated high-average-power, high-repetition-rate, femtosecond Ti:sapphire lasers with newly-invented intra-cavity or extra-cavity CW-amplification schemes. The maximum output powers reach 3.4 W and 5.8 W, respectively. Such high average power and high repetition-rate femtosecond optical pulses will open up new application possibilities including parametric frequency conversion, THz-emitter driver, and material processing. This cw-amplification scheme will be also widely applicable to other low-gain and laser-pumped gain media.
