| Abstract: | We present two kinds of ring cavities with phase conjugate mirrors. One cavity requires a tuning condition while the other one can oscillate independently of the cavity length. Both cavities have been experimentally studied using a sodium vapor phase conjugate mirror. Oscillations occur without any other gain medium inside the cavity. A strong correlation between the beams propagating in opposite directions in the cavity is observed. |
