Phase conjugation based on single backward second-order nonlinear parametric process

Yujie J. Ding

We show that backward difference-frequency generation can be exploited to achieve phase conjugation in a second-order nonlinear medium. The backward configuration can be utilized to achieve broadband quasi-phase-matching, compared with the forward counterpart. Our calculation shows that a nonlinear reflectivity of close to 100% is achievable from a laser emitting an output power of ~1 mW. Such an efficient phase conjugator is made feasible by placing the nonlinear medium inside a pump laser cavity. In addition, a Fabry-Perot resonator at the input frequency is used to significantly improve the nonlinear reflectivity.

Instantaneous phase conjugation at mW pump power based on backward differencefrequency generation

Yujie J. Ding

This study shows that a single second-order nonlinear process can be exploited to achieve phase conjugation. A reflection coefficient of close to 100% is achievable at the mW pump power based on backward difference-frequency generation. Moreover, large gains can be obtained, as the pump power is increased. All these powers are much lower than that for reaching backward optical parametric oscillation.
