Abstract

We present a review of our work on mirror-dispersion- controlled (MDC) Kerr-lens mode-locked (KLM) Cr:LiSGaF and Cr:LiSAF lasers, aimed at studying nonlinear phenomena in the 15-fs regime. Such effects as pulse self-frequency shift a side-band generation due to high-order dispersion (HOD), are looked at in more detail. These phenomena take place in any crystalline solitary mode-locked oscillator, and represent important limitations towards achieving ultimately short pulse durations.
