摘要

摘要对超短激光脉冲在硒化锌体中的高纳聚焦过程进行了研究。研究表明，当使用高孔径透镜将激光高斯光束聚焦到透明介质中时，会出现畸变，导致焦斑尺寸增大。实验研究结果表明，用微型透镜（NA = 0.55）聚焦的持续时间为 0.3、1、10 ps、波长为 1030 nm 的激光脉冲烧蚀了厚度为 4 mm 的 ZnSe 平面平行板的正面和背面。结果表明，在低脉冲能量下，聚焦可视为线性模式，其中焦斑大小是由像差畸变造成的。

High-NA Focusing of Ultrashort Laser Pulses in Bulk of ZnSe

A study of high-NA focusing process of ultrashort laser pulses in bulk of ZnSe has been carried out. It is shown that when focusing laser Gaussian beam with high-aperture lenses into a transparent medium aberration distortions occur leading to an increase in focal spot size. The results of experimental studies on ablation of front and back surfaces of a plane-parallel plate with 4 mm thickness made of ZnSe by laser pulses with a duration of 0.3, 1, 10 ps and a wavelength of 1030 nm focused by a micro lens (NA = 0.55) are presented. It is shown that at low pulse energies focusing can be considered in a linear mode in which focal spot size is due to aberration distortions.
