917~945 nm水汽吸收线线强度和空气加宽系数测量
High Resolution Absorption Spectroscopy of Water Vapor at 917~945nm: Measurements of Line Strengths and Air Broadening Coefficients
摘要
利用连续波窄带可调谐钛宝石激光器和长光程吸收池测量了917~945 nm 60余条水汽吸收线的强度和空气加宽系数。线强度测量精度优于4%,加宽系数测量精度优于6%。线强度结果和Chevillard等的测量结果比较,比值为0.986±0.0685,符合得较好。空气加宽系数和Hitran-92数据库比较,比值为0.906±0.164,存在较大的偏差。
Abstract
Water vapor high resolution spectroscopy were recorded with a cw narrow linewidth Ti∶Sapphire laser and a long pass absorption cell in 917~945 nm wavelength range. Measurements were made of line strengths with 4% uncertainty and air broadening coefficients with 6% uncertainty of 60 water absorption lines. Compared with Chevillard′s line strengths data, the agreement is good with average ratios of 0.0986±0.0685. However, the difference of air broadening coefficients is obvious between Hitran-92 database and ours, with average ratios of 0.0906±0.164.
