Abstract
Hermite‐Gaussian (HG), Laguerre‐Gaussian (LG), and Ince-Gaussian (IG) modes have been of considerable importance for photonics. They have revealed a unique way to optical manipulation and are particularly promising for optical communications. This paper combines HG modes, as a basis, inside the nonlinear crystal and the generated second harmonic field turns to LG and IG modes. Here we present a way to use second order nonlinear media to convert optical beam modes as we wish.
