Abstract

An analysis is made of the influence of changes in the density and polarizability of molecules on changes in the refractive index and tendencies of propagating of pulse laser radiation when the molecules in gas absorb or amplify resonant radiation. It has been shown that under absorbing or amplifying radiation in vibrational rotational transitions in the beam channel there may be formed a nonstationary focusing lens.
