Abstract
We are developing directly diode-pumped femtosecond lasers for industrial applications. A mode-locked Yb:KYW laser with the pulse duration of 113 fs has been developed as a seed laser. An Yb:KGW crystal in the regenerative amplifier is pumped by a 75-W fiber-coupled laser diode. The seed pulse was amplified to 0.82 mJ at the repetition rate of 1 kHz. At the repetition rate of 100 kHz, the averaged output achieved more than 3 W after pulse compression. The power stability during four hours was 1.56 % (3σ). We confirmed that the amplified pulse was compressed to nearly Fourier transform limit. The calculated transform limited pulse width and the measured pulse width was 319 fs and 339 fs, respectively.
