The generation of the second harmonic of Bessel light beams in quadratic-nonlinear crystals with radial-periodically domain structure was proposed and investigated. The type of interaction when the incident Bessel beam radially or azimuthally polarized is considered. A system of truncated equations for the field amplitudes of the fundamental and second harmonic fields is achiered. Numerically investigated The overlap integrals describing the efficiency of second harmonic generation were numerically investigated.
