The voigt profile
WebIn spectroscopy, the Voigt profile is a spectral line profile named after Woldemar Voigt and found in all branches of spectroscopy in which a spectral line is broadened by two types … WebFeb 1, 2024 · The Voigt profile [1] is of great importance in many fields in physics, such as optics, laser physics, radiative transfer, plasma, spectroscopy, and the optical functions of solids [ [2], [3], [4], [5]]. By the convolution of both the Lorentz and Gaussian profiles, the Voigt profile blends the physical characteristics of both profiles.

I need to write a code so that it plots the above function for different values of the a parameter, so that ultimately i will have a graph of 3 or more function of the form , , as functions of u. WebNo closed-form solution exists for the Voigt profile. It has been tabulated in the meteorological literature in terms of the parameter 2γ L /γ D . How the shape of the Voigt profile changes from pure Doppler broadening (γ L /γ D → ∞) to pure collision broadening (yL/yD → ∞) is also shown in Fig. 11-8 (for constant line half-widths).
