Spectral Characteristics of Ultrashort Pulses in Kerr-lens Mode-Locked Lasers

V. L. Kalashnikov, E. Sorokin, I. T. Sorokina

A number of factors that influence spectral position of the femtosecond pulse in a Kerr-lens modelocked Cr:LiSGaF laser have been identified: high-order dispersion, gain saturation…
