Abstract :
Summary form only given. Them has been continuous effort for obtaining high average-power, high-repetition-rate femtosecond pulses. Previously we had achieved 3.4-W average power from the mode-locked Ti:sapphire laser oscillator with an additional intra-cavity amplifier. We report a novel confocal double-pass, Ti:sapphire CW-amplifier with the 4.2 times small-signal gain and 10.6% extraction efficiency.
