In experimental studies of laser-plasma interactions, the laser radiation can exist inside plasma regions where the electron density is below the critical density (“underdense” plasma), as well as at the surface of the critical density. The surface of the critical density could exhibit a rich physics. Namely, the incident laser radiation can get converted in transverse electromagnetic waves of significantly higher amplitudes than the incident radiation, due to various nonlinear processes. We proposed a diagnostic method based on the laser-produced satellites of hydrogenic spectral lines in plasmas. The method allows measuring both the laser field (or more generally, the field of the resulting transverse electromagnetic wave) and the opacity from experimental spectrum of a hydrogenic line exhibiting satellites. This spectroscopic diagnostic should be useful for a better understanding of laser-plasma interactions, including relativistic laser-plasma interactions.

Model Calculations

The appearance of third charged particles groups has been fixed when the laser radiation interacted with metal target in rarefied environ gas. The intensity of opti-cal range laser radiation was ~109 W/cm2. The opportunity of using Langmuir probe for diagnosing plasma processes with nanosecond resolution has been demonstrated. The results of electron temperature measurements have agreed with results of estimate model calculations for the two fasted groups of particles in the absorbtion area (for experimental conditionals).
