Coherent superposition of the Laguerre-Gaussian beams with different wavelengths: colored optical vortices

Coherent superposition of the Laguerre-Gaussian beams with different wavelengths: colored optical vortices

We calculate the topological charge (TC) of a coherent axial superposition of different-"color" Laguerre-Gaussian (LG) beams, each having a different wavelength and TC. It is found that the TC of such a superposition is equal to the TC of the longer-wavelength constituent LG beam regardles...
