Abstract

The spectral characteristics of the Kerr-lens mode-locked Cr4+:YAG laser have been investigated both experimentally and theoretically. It was demonstrated that third-order dispersion provides a frequency downshift of the pulse spectrum (by as much as 70 nm) in combination with extra broadening (as much as 400 nm), in analogy with the generation of a spectral continuum in the fibers in the vicinity of zero-dispersion wavelength. The large redshift of the few optical cycle pulses (greater than 100 nm) and the dependence of the spectrum’s position on dispersion can be explained only if stimulated Raman scattering in the active medium is taken into account. It was shown that third-order dispersion can act as either a stabilizing or a destabilizing factor, depending on the amount of group-delay dispersion. Stabilization is found to be due to the negative feedback produced by the spectral sidebands.
