Paper Abstract

Parametric generation of light at pumping by Bessel light beam has been investigated. Advantages of such pumping over the use of Gaussian light beams have been revealed. A theory of azimuth-matched nonlinear interaction of Bessel light beams has been developed. It is shown that at such an interaction in the parametric generator the maximum coupling coefficient is realized and no destruction of the spatial structure of introcavity fields at high coefficients of conversion occurs. This opens up the possibility of increasing the energy conversion coefficient of the input Bessel beam compared to the Gaussian beam.
