Quantitative Analysis of Doppler-Free Spectra via the Collisional-Radiative Model

Year: 2025

Type: article

Abstract: We have constructed a simulation model of the Doppler free spectra for the hydrogen Balmer α line. We are introducing the laser excitation process into the collisional-radiative model of hydrogen atoms to see how much saturation can be achieved under realistic plasma conditions and laser power density. Results show that the simulated spectra were able to successfully model Lamb dips and peaks utilizing this method, with the simulated plasma and laser parameters showing good agreement to the ones used in the experiment. This model has additionally helped illustrate further insight into how plasma parameters can affect the spectral characteristics of Lamb dips and peaks.
