چکیده
Based on the second-order moments definition, beam propagation factor of a new mathematical model Hollow higher-order Cosh-Gaussian (HhCG) beams is investigated. Analytical formula for M2-factor HhCG derived, which depends hollowness parameter l, order n, cosh part δ and waist ω0. The influences these parameters are illustrated with numerical examples. result provides more general characteristics because Cosh-Gaussian, Gaussian obtained as specials cases beams.

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...
متن کاملRelay 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...
متن کاملPropagation-invariant beams with quantum pendulum spectra: from Bessel beams to Gaussian beam-beams.
We describe a new class of propagation-invariant light beams with Fourier transform given by an eigenfunction of the quantum mechanical pendulum. These beams, whose spectra (restricted to a circle) are doubly periodic Mathieu functions in azimuth, depend on a field strength parameter. When the parameter is zero, pendulum beams are Bessel beams, and as the parameter approaches infinity, they res...
متن کاملGeneralized beam quality factor of aberrated truncated Gaussian laser beams.
We outline a theory for the calculation of the beam quality factor of an aberrated laser beam. We provide closed-form equations that show that the beam quality factor of an aberrated Gaussian beam depends on all primary aberrations except tilt, defocus, and x-astigmatism. The model is verified experimentally by implementing aberrations as digital holograms in the laboratory.
متن کاملNumerical 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...
