It-radiance-dependent transmission measurements were conducted for thin Csc film irradiated by 300 fs laser pulse at 6 12 nm in the intensity range from lo8 W/cm\* to the values Y lOI W/cm2 corresponding to the film damage. The upper limit for the two-photon absorption coefftcient was derived from t
