We demonstrate second-harmonic generation from a ( 110 ) ZnSe crystal for focused, axially symmetric polarized beams. Distinctive distributions in polarization and intensity accompanying transverse mode conversion to higher-order Hermite–Gaussian or Laguerre–Gaussian modes are observed. A longitudinal electric field generated by a radially polarized beam is verified by the variation in the intensity distribution.
