The Quasi-Phase Matching of Airy Beam

We demonstrate the Airy beam, propagating through a periodically poled nonlinear crystal, could significantly increase the conversion efficiency during the quasi-phase-matched (QPM) process.

Description
Summary:We demonstrate the Airy beam, propagating through a periodically poled nonlinear crystal, could significantly increase the conversion efficiency during the quasi-phase-matched (QPM) process. Meanwhile, the so-called co-Airy beams can be signed as a conjunction of two Airy beams by binding their collinear lateral lobes with appropriate parameters. With the help of the phase-matched modulation, the two Airy beams are united and compressed by the parameters. The set of parameters determines the direction of the “force” that the structure distribution of the co-Airy beams be pressed. We hope that our work will contribute to the generation of multi-Airy beams and further enhancement of research on Airy beam control using quasi-phase-matched crystals.
