Abstract

There 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 amplifier¹. In this presentation, we will report a novel confocal double-pass, Ti:sapphire cw-amplifier with the 4 2 times small-signal gain and 10 6 % extraction efficiency
