Hermite gaussian beam
WitrynaFollowing, Hermite-Gauss beams with complex arguments in the Hermite functions (also called “elegant” Hermite-Gaussian modes in the literature [1, 5, 6]) are derived by differentiating the fundamental Gauss mode with respect to the transverse coordinates. Next, it is shown how this derivation can be generalized to obtain a whole family of ... WitrynaSome of these approaches are limited to a certain alphabet, while others tend to fall short when considering optical beams with non-trivial structure, such as Hermite-Gauss, Laguerre-Gauss and ...
