The intracavity laser spectroscopy (ILS) technique has been shown to be a very sensitive method for observing absorption spectra. By considering quantitative results (line-strengths and pressure broadening coefficients) obtained using the ILS method with a dye laser, the technique has been shown to provide quantitative information that is in excellent agreement with the values afforded by use of more traditional methods for acquiring absorption spectra. A similar investigation has been conducted for an ILS system based on a Ti:sapphire laser. Presented here are quantitative results for water vapor transitions occurring around 795 nm. Line intensities are determined as a function of water vapor pressure and effective path length (i.e., generation time). The line-strengths are compared with values determined by R. A. Toth [J. Mol. Spectrosc. 166, 176-183 (1994)] who used a multipass cell and the Fourier transform spectrometer at the Kitt Peak National Observatory. The good agreement between the results demonstrates that quantitatively accurate data can be obtained using the ILS technique with a Ti:sapphire laser. Copyright 1998 Academic Press.

使用钛蓝宝石激光器进行定量腔内激光光谱测量：790–800 nm 区域内水蒸气谱线的吸收强度

腔内激光光谱 (ILS) 技术已被证明是观察吸收光谱的一种非常灵敏的方法。通过考虑使用染料激光器的 ILS 方法获得的定量结果（线强度和压力展宽系数），该技术已被证明提供的定量信息与使用更传统的获取吸收方法所提供的值非常一致光谱。对基于钛蓝宝石激光器的 ILS 系统进行了类似的研究。这里展示的是发生在 795 nm 附近的水蒸气跃迁的定量结果。线强度被确定为水蒸气压力和有效路径长度（即生成时间）的函数。线强度与由 RA Toth 确定的值进行比较 [J. 摩尔。光谱c。166, 176-183 (1994)] 谁在基特峰国家天文台使用了多通道池和傅立叶变换光谱仪。结果之间的良好一致性表明，使用 ILS 技术和 Ti:sapphire 激光器可以获得定量准确的数据。版权所有 1998 学术出版社。
