Abstract

In this paper properties of the generation of difference frequency of Bessel light beams at the quasi-synchronous interaction in periodically poled nonlinear crystals are investigated. The angular width of the synchronism for collinear and vectorial interactions under condition of first-order quasi-synchronism is defined. It is shown that in periodically poled nonlinear KTP crystals where the maximum nonlinear coefficient (sigma) ₃₃ is used, an effective generation of difference frequency of Bessel light beams takes place, which is in contrast with homogeneous media.
