We present an extensive investigation of the polarization properties of a femtosecond-laser-induced white-light (WL) continuum generated in a cubic crystal ( CaF 2 ) . The WL spectrum and threshold energies have been examined for input polarizations with various degrees of ellipticity. For linear input polarization, the WL spectrum shows strong depolarization around the input wavelength, while the preservation of the input polarization is pronounced toward the blue spectral region. The observed depolarization effect has been elucidated in the framework of current models for WL generation.

  23. The obtained ratio between the WL energy thresholds for circular and linear polarization is ∼3/2, which matches the ratio between the corresponding nonlinear indices of refraction (n2). It is relevant for our experimental observations and also that for other groups that WLG threshold power is slightly above the SF threshold, i.e., it is also proportional to ∼1/n2.
