We demonstrate both analytically and experimentally that second-order nonlinear interaction in a uniaxial crystal produces a holographic replica of one of the incident fields. In particular, we consider differencefrequency generation and directly calculate the field transformation that is produced by the nonlinear interaction for some simple but nontrivial two-dimensional objects, such as a long wire, a circular hole, and a regular net. Finally we show experimental results for such objects that validate the theoretical calculations.

“…Due to the presence of the signals and idlers having perpendicular polarizations, such a nonlinear process is insensitive to the polarization of the input beam. In the past, theoretical and experimental studies of three-wave interaction had been investigated in different nonlinear crystals, such as theoretical study of difference-frequency generation (DFG) in β-BaB 2 O 4 (BBO) for different angles between the input and pump beams [10], experimental and simulation work on the quality of phase conjugate affected by the flatness of pump wave front [11], and phase conjugated beams generated by a transversely pump beam [12,13]. However, all of them suffer from a major disadvantage, i.e.…”

We review our previous result: 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-phasematching, 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 cavity at the input frequency is used to significantly improve the nonlinear reflectivity. In our previous experimental result, we demonstrated that broadband and polarization-insensitive phase conjugation, achieved based on difference-frequency generation in a second-order nonlinear composite consisting of stacked KTP plates, was exploited to restore blurred images due to phase distortion as a novel scheme. Due to the quasi-phase matching in the stacked KTP crystals, our result reveals that the image restoration is insensitive to the polarization direction and wavelength of the input beam.

Broadband and polarization-insensitive phase conjugation, achieved based on difference-frequency generation in a second-order nonlinear composite consisting of stacked KTiOPO(4) (KTP) plates, was exploited to restore blurred images due to phase distortion as a novel scheme. Due to the quasi-phase matching in the stacked KTP crystals, our result reveals that the image restoration is insensitive to the polarization direction and wavelength of the input beam.
