Abstract
In this work, we study the nonlinear absorption of ultrashort laser pulses of variable duration (0.3‒10 ps) in a bulk polycrystalline ZnSe dielectric. The transmission of the sample was measured for two wavelengths, 515 and 1030 nm, in a wide range of intensities. A nonlinear behavior of the transmission is found when the sample is irradiated with laser radiation at a wavelength of 515 nm with absorption saturation in the region of 3–5 TW/cm2. Surface damage thresholds were obtained for a wavelength of 1030 nm for pulse durations of 0.3–10 ps.
