Abstract

We are developing a multi-kHz repetition rate high-average power Ti:sapphire regenerative amplifier as a pumping laser of a laser-plasma X-ray source. With an optimally designed ring resonator with a cryogenically-cooled laser rod, the average output power of 54 W before compression was achieved when pumped by a 180-W green laser at 10 kHz repetition rate. The focusability of the output beam was better than two times of the diffraction limit and can be compressed to 82 fs. Possibility of scaling to higher output power is discussed.
