摘要/Abstract

摘要： 基于高分辨率可调谐二极管激光吸收光谱仪（TDLAS）和长程怀特吸收池搭建了一套高分辨率、光程可调吸收光谱测量系统，采用直接吸收光谱技术测量了1.51 µm 波段（6608~6624.3 cm-1）水分子室温下的吸收光谱。利用非线性拟合程序，获得了57条水分子吸收谱线的线位置、线强和自展宽系数，并与HITRAN 2016数据库中的相应数据进行了比较，结果表明整体实验数据与HITRAN 2016符合较好，证明该光谱测量系统适用于水分子吸收谱线参数研究。

Abstract: The absorption spectrum of natural abundance water vapor at 1.51 µm has been studied at room temperature, by using a high-resolution tunable diode laser absorption spectrometer (TDLAS) combined with a long-path White absorption cell. A total of 57 absorption lines are investigated within the laser spectral range (6608~6624.3 cm-1). The line positions, line intensities and self-broadening coefficients of these lines are obtained by using a nonlinear least-squares fitting method, and then compared with the available values reported in the HITRAN 2016 database. Results show that the experimental data of present work is in good agreement with those from HITRAN 2016 database, which indicates that the spectral measurement system is suitable for study on the spectra of water vapor.
