一、引言计算机控制的高分辨率可调谐环形染料激光光谱仪由以下几部分组成,如(图1)示,其中包括环形染料激光器、稳频系统及计算机控制部分。它的特点是谱线宽度窄,具有超高光谱分辨率;频率漂移小;它的频率在很大范围内连续可调谐(从兰410毫微米至近红外960毫微米);并且可以采用计算机控制在一定的范围内对频率进行十分精确的调谐。
I. Introduction Computer-controlled high-resolution tunable ring dye laser spectrometer consists of the following parts (Figure 1), including ring dye laser, frequency stabilization system and computer control part. It features narrow spectral lines with ultra-high spectral resolution; small frequency drift; its frequency is continuously tunable over a wide range (from 410 nm to 960 nm); and it can be computer controlled The frequency is tuned very accurately within a certain range.
