title: Femtosecond regenerative amplification in Cr:forsterite.
abstract: We describe an oscillator-amplifier laser system for the generation of high-power femtosecond pulses near 1.25 microm based on chromium-doped forsterite. Chirped-pulse amplification at a 1-kHz repetition rate raises the pulse energy to >350 microJ. The nearly transform-limited 200-microJ, 135-fs-long recompressed pulses have a peak power of approximately 1.5 GW.
