- Аннотация: We obtained significant reducing in amplitude of pre-pulses before main femtosecond pulse in Cr:forsterite amplifier beam, self- reflected at high intensity from silicon plate at Brewster angle without any beam distortion. Reflection efficiency was 40% at optimal intensity of 3 TW/cm2, and could be explained by free-carrier generation from two-photon absorption at 1240 nm.
