The Hermite—Gauss and Laguerre—Gauss modes are well-known beam solutions of the scalar Helmholtz equation in the paraxial limit. As such, they describe linearly polarized fields or single Cartesian components of vector fields. The vector wave equation admits, in the paraxial limit, of a family of localized Bessel—Gauss beam solutions that can describe the entire transverse electric field. Two recently reported solutions are members of this family of vector Bessel—Gauss beam modes.
