摘要

本文介绍了一种用于研究激光对包括生物组织在内的各种材料的作用过程的仪器。该系统可在实验过程中获取样品表面的热图、进行高速视频记录和记录宽频率范围的声学信号。该系统使用波长为 3.03 μm 的脉冲纳秒高频激光源进行测试。样品受到持续时间为 1.5 毫微秒、频率为 8 兆赫的脉冲照射。实验结果表明，使用激光系统可以在各种类型的生物组织上获得切口，而不会造成碳化。所获得的实验数据使我们有可能弄清激光辐射对水饱和生物组织表面的作用机理。

An Apparatus for Studying the Laser Radiation Effects on Biotissue

An apparatus for studying the processes of laser action on various materials, including biological tissue, is described. The system makes it possible to obtain thermograms of the sample surface, conduct high-speed video recording, and record acoustic signals in a wide frequency range during experiments. The system was tested using a pulsed nanosecond high-frequency laser source with a wavelength of 3.03 μm. The samples were exposed to pulses with a duration of 1.5 ns and a frequency of 8 MHz. It is shown that it is possible to use a laser system to obtain incisions on biological tissues of various types without carbonization. The obtained experimental data made it possible to clarify the mechanism of the action of laser radiation on the surface of water-saturated biological tissues.
