Numerical Calculation of Coupling Efficiency for an Elegant Hermite-Cosh-Gaussian Beams
The ABCD matrix method is used to simplifying the theoretical coupling efficiency calculation of Elegant Hermite-Cosh-Gaussian (EHChG) laser beams to a Single Mode Fiber (SMF) with a quadric lens formed on the tip. The integrals of coupling efficiency relation are calculated numerically by Boole method. Meanwhile, the structure parameters of surface-lensed fiber are optimized in numerical simul...
متن کاملScintillation characteristics of cosh-Gaussian beams.
By using the generalized beam formulation, the scintillation index is derived and evaluated for cosh-Gaussian beams in a turbulent atmosphere. Comparisons are made to cos-Gaussian and Gaussian beam scintillations. The variations of scintillations against propagation length at different values of displacement and focusing parameters are examined. The dependence of scintillations on source size a...
متن کاملFocusing of spherical Gaussian beams.
Simple procedures and formulas for tracing the characteristics of a spherical Gaussian beam through a train of lenses or mirrors are described which are analogous to those used in geometrical optics to trace repeated images through an optical train.
متن کاملGaussian, Hermite-Gaussian, and Laguerre-Gaussian beams: A primer
The paper aims at presenting a didactic and self-contained overview of Gauss-Hermite and Gauss-Laguerre laser beam modes. The usual textbook approach for deriving these modes is to solve the Helmoltz electromagnetic wave equation within the paraxial approximation. Here, a different technique is presented: Using the plane wave representation of the fundamental Gaussian mode as seed function, all...
متن کاملAxicon Gaussian Laser Beams
If a laser beam is to have radial transverse polarization, the transverse electric must vanish on the symmetry axis, which is charge free. However, we can expect a nonzero longitudinal electric field on the axis, considering that the rays of the beam that converge on its focus each has polarization transverse to the ray, and hence the projections of their electric fields onto the axis all have ...
