We demonstrate a scalable approach for the generation of high average power femtosecond (fs) pulse trains from Ti:sapphire by optically injection locking a resonant amplification cavity. We generate up to 7 W average power with over 30% optical extraction efficiency in a 68 fs pulse train operating at 95 MHz. This master oscillator power amplifier approach allows independent optimization of the fs laser while enabling efficient amplification to high average powers. The technique also enables coherent synchronization among multiple fs laser sources.
