Abstract
It is an important method to measure the concentration of methane(CH4)by using 1.6μm laser differential absorption.By analyzing and calculating the absorption spectrum of CH4,based on a tunable Er∶YAG single frequency laser,the absorption of CH4 towards 1.645μm laser is measured experimentally.The results are useful for selecting the LIDAR's source for measuring the concentration of CH4.

期刊介绍：
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
