Continuum Radiation Absorption in Resonant Expanding Gas Media

  • Quantum Electronics
  • Published:
Russian Physics Journal Aims and scope

The absorption of external radiation and continuum radiation originating from the center in a self-similar expanding gas sphere is considered. The frequency and integral probabilities of radiation absorption in a resonance frequency domain are analyzed depending on the expansion velocity gradient and the optical thickness of the medium. It is demonstrated that the optical density of the medium decreases and the integral absorption increases in the expanding medium.
