|Title:||Interaction of 4 μm laser beam with absorption lines of sulphur dioxide|
|Authors:||Barua, A Gohain|
|Keywords:||Sulphur dioxide lines;Quasi-random model;Free electron laser;Transmittance|
|Abstract:||Interaction of a free electron laser beam of wavelength 4 μm with rotational lines of sulphur dioxide has been studied. Values of transmittance, averaged over intervals of 0.1 cm⁻¹, are obtained for absorber thickness 0.01, 0.1 and 1 atm-cm, using the quasi-random model of molecular band absorption. From these values, intensities of the high resolution absorption lines of SO₂ are simulated in the frequency interval 2499.0115 – 2499.9910 cm⁻¹.|
