摘要：

We present a comprehensive study of the optimum operating regime in a gain-switched Cr : forsterite laser at a repetition frequency of 1 kHz with special attention to temperature-dependent and parasitic absorption effects and proper resonator design. On the basis of the results achieved, we demonstrate highly efficient (13% extraction efficiency) operation of a femtosecond regenerative amplifier based on Cr : forsterite and operating near room temperature with a novel BBO Pockels cell that is highly resistant to optical damage. Chirped pulse amplification raises the pulse energy to 355 mu J in approximate to 30 cavity round trips which corresponds to an amplification factor of approximate to 5.5 x 10(5), The nearly transform limited 200-mu J 135-fs compressed pulses near 1.25 mu m have a peak power of approximate to 1.5 GW. Frequency doubling with 52% conversion efficiency in LBO produces femtosecond pulses of 104-mu J energy in the visible near 625 nm.
