摘要：

Theoretical treatment of nonlinear, three-wave interaction and second harmonic generation (SHG) of Bessel fundamental beams in case of collinear phase matching is reported. The expressions of power and conversion efficiency of SHG of Bessel fundamental beams are found. We also demonstrate operation of SHG pumped by a Nd:YAG Bessel beam using KD*P nonlinear crystal. It is shown that the output of SHG of Bessel beam has a transverse profile and its conversion efficiency is higher than that of the Gaussian beam.
