Paper Abstract

The problem of diffraction limited laser beam generation in gas flow CO2 lasers of high power turned out to be rather complicated because of a number of factors that are of physical or technical nature. The ultimate solution to the beam quality problem in these lasers would be the use of phase conjugation to compensate simultaneously for the most of laser beam distortions along the optical train of the laser. The main point, in which the situation with the development of phase conjugate mirrors for CO2 lasers differs from one for lasers of visible and near infrared regions of spectrum is that the use of four-wave mixing in a nonlinear medium is the only technique of phase conjugation available in this region of wavelengths. In this paper an attempt is made to present some results of experimental investigations of four-wave mixing phase conjugation in CO2 lasers, which have been obtained at S. I . Vavi by Opt ical Inst itute , Leningrad, USSR.
