摘要
本文利用Cr:LiCAF可调谐激光器,经BBO晶体倍频,获得了8～mJ、34～ns、370～nm的巨脉冲激光；并利用370～nm激光激发离体结肠癌组织和正常组织进行组织的自体荧光实验,并作了对比和分析,获得了对结肠癌变的早期诊断的很有价值的荧光光谱。
Abstract
In this paper, 370～nm laser is produced with its energy 8 J and pulsewidth 34～ns by using a Q-switched and frequency-doubled Cr:LiCAF laser system. Then, we use 370～nm laser as exciting light source to analyze the auto-fluorescence spectra of the solid samples of large intestine carcinoma and normal large intestine tissue, and gain the very valuable auto-fluorescence spectra for early detection of precancerous changes in colon tissue.
