Generation of 33-fs pulses from a passively mode-locked Cr(3+):LiSrAlF(6) laser.
Femtosecond and picosecond operating regimes of an argon-ion-pumped Cr(3+):LiSrAlF(6) laser, passively mode locked using a saturable absorber, are described. At low absorber concentrations, self-starting cw mode locking is demonstrated, which yields pulses as short as 33 fs after extracavity prism compensation. At higher concentrations, both cw mode-locked and Q-switched mode-locked operation is possible. the recovery time of the absorber is discussed.
