Regenerative amplification of 30-fs pulses in Ti:sapphire at 5 kHz.
18-fs pulses from a self-mode-locked Ti:sapphire laser are amplified to 60 microJ of energy at 4.9 kHz with chirped-pulse amplification in a Ti:sapphire regenerative amplifier. After recompression, 30-35-fs, near-transform-limited pulses are obtained.
