Overview

Using femtosecond laser-induced breakdown spectroscopy reveals unique spectral signatures in low-density gases, indicating density extraction is feasible.

Key Points

  • Unique spectral signatures were detected for H2, CH4, CO2, and H2O at low densities, highlighting its versatility.
  • The analysis employed Voigt lineshape fitting to characterize the LIBS intensity response across varying densities.
  • Testing gas mixtures demonstrated the potential for extracting individual gas densities, which can be crucial for various applications.
  • Strong molecular and atomic features were observed in the LIBS spectra, providing insights into gas composition and behavior.
