A new kind of laser beam called the decentred elliptical flat-topped light beam (DEFTB) is introduced in this paper by using a tensor method. Based on the generalized Collins integral, the propagation formula for a DEFTB passing through an axially nonsymmetrical paraxial optical system is derived through vector integration. The derived formula can be reduced to the formulae for the generalized decentred elliptical Gaussian beam and elliptical flat-topped light beam under certain conditions. As a typical application example of the derived formula, the propagation characteristics of a DEFTB in a thin lens system are calculated and discussed. Furthermore, the generalized laser beam arrays with rectangular symmetry and radial symmetry by using DEFTBs as fundamental modes are constructed and the propagation properties of both a coherent and an incoherent combination of DEFTBs in the thin lens system with numerical examples are investigated.

“…Laser array beams are widely used in fields such as the high energy weapons, high-power laser systems, and free space optical communications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The propagation properties including beam spreading, M 2 -factor, Rayleigh range, effective radius of curvature of laser array beams propagating through free space and ideal turbulent atmosphere have been investigated in detail [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Based on the extended Huygens-Fresnel principle, the definition of second-order moments of the Wigner distribution function (WDF), and the non-Kolmogorov turbulence spectrum, analytical expressions for the M 2 -factor and Rayleigh range of correlated combination partially coherent Hermite-Gaussian linear array (PCHGLA) beams propagating through non-Kolmogorov turbulence have been derived. The effect of non-Kolmogorov turbulence and array beam parameters on the M 2 -factor and Rayleigh range is discussed in detail. The results show that the M 2 -factor and Rayleigh range, as well as their corresponding relative quantities of the PCHGLA beams, vary non-monotonically with increasing generalized exponent parameter α of the turbulence, and M 2 -factor exists a maximum whereas Rayleigh range exists a minimum at α = 3.11, respectively. The M 2 -factor and Rayleigh range of PCHGLA beams increase with increasing beam number but oscillate with increasing relative beam separation distance x 0 0 for x 0 0 < 1 and then increase monotonically as x 0 0 increases for x 0 0 > 1. The PCHGLA beams are less affected than the GSM linear array beam under the same conditions.
