For the infrared spectrum detection techniques, the … NettetThe line shape function g(ν) spectrally governs the rate of spontaneous and stimulated emission. The stimulated transition rate per atom is given by W i = λ 2 I ν g (ν)/(8π n 2 h ντ), where n is the refractive index and I ν is the intensity (W cm -2 ) of the monochromatic optical wave (at frequency ν) causing stimulated emission.

The line type function ϕ (ν) can take three different form of function: Gaussian, Lorentzian, and Voigt [26, 27]. 2.4 Line-shape function selection. The DLAS analyzer was operated at an atmospheric pressure (1 atm) and room … NettetA line laser is a device that employs a laser and an optical lens to project the laser beam as a line rather than a point (e.g. laser pointer).This may be achieved by passing the …
NettetThus the laser is not purely monochromatic, its power spectrum showing a broadened lineshape rather than a Dirac delta function. The lineshape and linewidth depend on the … NettetChapter (4) Spectroscope of the laser light LASER 21 There are two general classification of line broadening: Homogenous: all atoms behave the same way (i.e., each effectively has the same g(ν). Inhomogeneous: each atom or molecule has a different g(ν) due to its environment. i.e. Broadening is Homogeneous when it affects all “atoms” equally and …
NettetThe gas detection method based on the tunable laser absorption spectroscopy is considered a promising technique. For the infrared spectrum detection techniques, the line shape function of an absorption spectrum of a gas is an important parameter in qualitative and quantitative analysis of a gas.
