Paper Abstract

The change of refractive coefficient of active gas medium in pulsed chain chemical HF-laser due to temporal variations of chemical composition and populations of vibrational states HF(v) and H2(v)-molecules is analyzed. These changes are related to different polarizability of components of the chemical laser medium and the dependence of polarizability on vibrational state population for atomic and electronic constituents of polarizability. The atomic polarizability is characterized by sizable frequency dispersion. The change of reflective coefficient due to the change of vibrational excitation is a nonline effect, since the vibrational excitation depended on intensity of the laser beam.
