- Descripción
- This work presents the development and validation of a computational algorithm that aims to adjust isolated lines of an optical spectrum, obtaining the values {}{}for the parameters of a Voigt or Pseudo-Voigt profile. The recovery of these parameters is important for the study of the emission spectrum of plasma produced by laser. The tested spectra were well approximated by the fitted functions, and the fit routine showed to be very promising for isolated spectral lines. The method is evaluated and tested using simulated lines and applied to experimental data from the \textit{H$\alpha$ }line (656.273 \textit{nm}) of hydrogen. Adjustment parameters were used to determine plasma density and temperature.
