Abstract :
Summary form only given. We present, to our knowledge, the first results of a very compact femtosecond laser delivering sub-100-fs pulses with almost 300-MHz repetition rate approaching the 100-mW level. Our Kerr-lens mode-locking setup employs a 5-mm-long, 2.2%-doped Cr:LiSAF crystal and a pair of identical Gires-Tournois interferometer mirrors (GTI) to compensate the positive group velocity dispersion (GVD) of the gain medium. GTI mirrors were chosen because of the larger amount of negative GVD together with lower scatter loss compared to chirped mirrors.
