Paper Abstract

The term Helmholtz-Gauss beam refers to a field whose disturbance at the plane z =0 reduces to the product of the transverse field of an arbitrary nondiffracting beam (i.e. a solution of the two-dimensional Helmholtz equation) and a two-dimensional Gaussian function. In this work, the transverse shape and the propagation of Helmholtz-Gauss beams is experimentally studied for the four fundamental orthogonal families of Helmholtz-Gauss beams: cosine-Gauss beams, Bessel-Gauss beams, stationary and helical Mathieu-Gauss beams, and stationary and traveling parabolic-Gauss beams. The power spectrum of the Helmholtz-Gauss beams is also recorded and its intensity distribution is assessed. Potential applications are discussed.
