Paper Abstract

The theoretical calculation for nonlinear refractive index n2 in Cr2+:ZnSe-active medium predicts the strong defocusing cascade second-order non-linearity within 2-3 micrometers spectral range. On the basis of this result the optimal cavity configuration for Kerr-lens mode locking is proposed that allows to achieve a sub-100 fs pulse duration. The numerical simulations testify about strong destabilizing processes in the laser resulting from a strong self-phase modulation. The stabilization of the ultra short pulse generation is possible due to spectral filtering that increases the pulse duration up to 300 fs.
