Abstract

A phase-conjugate (PC) mirror on the basis o InAs in a cavity o a TEA CO2 laser was studied. Efficiency B o such a PC-mirror is 1O% ror the signal coherent to the pump waves and 3-5% ror the incoherent signal. The PC fidelity or a signal wave in the scheme studied is shown to be as high as 1 00%. The insertion of Inks plate into the laser cavity is round to result in : i) the stretching o the FWIIM pulse duration, ii) the stabilization of the mean intracavity radiation intensity, iii) the Lonnation o the hypergaussian intracavity beam profile due to strong nonl inear absorp t ion in Inks ; and due to the nonl inear change of index in Inks iv) the diffraction of the laser radiation on intracavity apertures and v) the transition from periodic to chaotic pulsations of the output power.
