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.

用于浸入式应用的块状硒化锌的光学非线性特性研究

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。
