Numerical Calculation of Coupling Efficiency for an Elegant Hermite-Cosh-Gaussian Beams

Authors

Abstract:

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 simulation to achieve maximum coupling efficiency. Results can give some guidance suggestions for designing suitable micro lenses in order to coupling the EHChG laser beams to the SMF.

Scintillation 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...

Gaussian, 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...

An Elegant Deadline Calculation for SCED

The future multimedia Internet needs mechanisms to provide QoS (Quality of Service) for users. Service curve (SC) is an effective description of QoS and SCED (service curve based earliest deadline first policy) is an efficient scheduling algorithm to guarantee SCs specified by users. Deadline calculation is the core of SCED. The unique treatable SC as we know is the concave piecewise linear SC ...

Calculation of Synthetic Seismograms with Gaussian Beams

In this paper, an overview of the calculation of synthetic seismograms using the Gaussian beam method is presented accompanied by some representative applications and new extensions of the method. Since caustics are a frequent occurrence in seismic wave propagation, modifications to ray theory are often necessary. In the Gaussian beam method, a summation of paraxial Gaussian beams is used to de...

Numerical Calculation of Coupling Impedances in Kicker Modules for Non-Relativistic Particle Beams

Open boundary conditions. Since the source current, Eq. 1, extends from z = −∞ to +∞ whereas our computational domain is finite, one has to apply suitable boundary conditions (see also [2]). Consider some accelerator component, residing in a vacuum cavity with attached beam pipe of smaller cross section than the cavity. Generally, the transitions from the pipe to the module have to be included ...

Relay Propagation of Partially Coherent Cosh-gaussian Beams in Non-kolmogorov Turbulence

The analytical formulas for the average intensity and power in the bucket of the relay propagation of partially coherent cosh-Gaussian (ChG) beams in non-Kolmogorov turbulence have been derived based on the extended Huygens-Fresnel principle. The influences of the beam parameters, relay system parameters and the non-Kolmogorov turbulence parameters on relay propagation are investigated by numer...
