Abstract

A detailed experiment on phase conjugation via degenerate four-wave mixing in LiF:F₂^- and NaF (F₂⁺)^* crystals pumped by pulse-periodic Nd:YAG laser is described. The dependence of the efficiency of phaser conjugation on the energies and polarizations of the interacting beams and on the concentration of F₂^- CC is described. The mechanism of phase conjugation is connected with the saturation of the absorption in the color center crystals. Phase conjugation was investigated in LiF:F₂^- crystals that worked simultaneously as a passive Q-switch of a Nd:YAG laser. This allows use of the LiF:F₂^- crystal as a phase conjugated mirror of a Nd:YAG laser.
