    "abstract": "The theoretical calculation for nonlinear refractive index in Cr: ZnSe -\nactive medium predicts the strong defocusing cascaded second-order nonlinearity\nwithin 2000 - 3000 nm spectral range. On the basis of this result the optimal\ncavity configuration for Kerr-lens mode locking is proposed that allows to\nachieve a sub-100 fs pulse duration. The numerical simulations testify about\nstrong destabilizing processes in the laser resulting from a strong self-phase\nmodulation. The stabilization of the ultrashort pulse generation is possible\ndue to spectral filtering that increases the pulse duration up to 300 fs.",
