ABSTRACT:
A passive (self-pumped) phase conjugate mirror uses a third-order nonlinear polarization medium, either of the refractive type (effective nonlinear) or the actual nonlinear type, with an optical system of one or more mirrors to reflect back through the medium a coherent incident beam diffracted by the medium. With two mirrors, they may be aligned to form a linear optical cavity containing the nonlinear medium, or they may be so oriented on one side of the medium that the incident beam transmitted through the medium is reflected back through the medium at an angle with the incident beam, and diffracted light from the incident beam is reflected back through the medium in the opposite direction coincident with the incident beam. A passive phase conjugate mirror may replace an end mirror of an optical cavity for a laser gain medium. Phase distortions of the laser beam in the laser cavity are corrected by the passive phase conjugate mirror.
