Abstract
Over the last few years the chromium-doped forsterite (Cr4+:Mg2SiO4) laser has been developed as reliable source of generating ultrashort pulse at the near-infrared region.1-5 Varying repetition rate is important to avoid the accumulating effect of signal overlaps due to high repetition rates (~100 MHz) in many experiments. Incorporating a cavity dumper in the laser resonator is a simple and convenient method of providing medium-to-high peak power with a variable repetition rate.6 The cavity-dumped Ti:sapphire laser systems were successfully demonstrated by Ramaswamy et al.7 and Pshenichnikov et al.8 to producing pulse durations of 10-50 fs with pulse energies of 100 nJ at variable repetition rates.
