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