1TW, 10Hz及び0.1TW, 1kHz全固体フェムト秒レーザーの開発 1TW, 10Hz and 0.1TW, 1kHz All-Solid-State Femtosecond Lasers
We have designed and developed two types of all-solid-state femtosecond Ti: sapphire laser systems by using diode-pumped Nd: YAG green laser systems as pump sources. One is a high-peak-power femtosecond laser system with a peak power of 1.1 TW, a pulse duration of 74 fs, and a beam quality factor M<SUP>2</SUP>≤1.4 at a repetition rate of 10 Hz, the other is a high-repetition-rate femtosecond laser system with an average power of 10.1 W, a peak power of 0.1 TW, a pulse duration of 100 fs, and a beam quality factor M<SUP>2</SUP>≥1.5 at a high repetition rate of 1 kHz. We also discuss the development of the diode-pumped Nd: YAG green laser systems for pumping these Ti: sapphire laser systems.
