Polarization properties of SC generated in CaF2

Polarization of SC generated by 80 fs pulses of Ti:Sapphire laser strongly depends on the orientation of CaF2 plate with respect to the plane of polarization of the pump light. Intensity modulation of the broad blue-shifted wing of SC against crystal rotation for the polarization parallel and orthogonal to the polarization of the pump beam is observed with CaF2 and Sapphire. Observed modulation is due to evolution of the polarization state along the propagation distance in crystal.
