摘要

摘要在这项工作中，我们研究了持续时间可变（0.3-10 ps）的超短激光脉冲在块状多晶硒化锌电介质中的非线性吸收。我们测量了样品在 515 纳米和 1030 纳米两种波长、多种强度下的透射率。当用波长为 515 纳米的激光辐射照射样品时，透射率出现非线性行为，吸收饱和度为 3-5 TW/cm2。在波长为 1030 nm、脉冲持续时间为 0.3-10 ps 时，获得了表面损伤阈值。

The Study of the Optical Nonlinear Properties of Bulk ZnSe for Immersion Applications

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.
