“…This was found to be a good approach to describe the beam field throughout the aperture [20]. In recent years the complex Gaussian functions expansion method proposed by Wen and Breazeale has been widely used to study propagation properties of truncated laser beams [20][21][22][23][24][25]. In this paper, the divergence problem of the M 2 factor of truncated laser beams is avoided by using the complex Gaussian functions expansion method; the analytical expression for the M 2 factor of truncated Gaussian beams is derived.…”

“…Cai et al proposed a elliptical flat-topped beam to describe an elliptically symmetric flat-topped beam by expressing its electric field as a finite sum of astigmatic, elliptical Gaussian beams [6] . However, at present, most studies on flattopped beams have been confined to circular, flattopped beams, while research on square, flat-topped, spatial-profile beams has been scarce [7][8][9][10][11][12][13][14][15][16][17] . Partially coherent, square, flat-topped pulsed beams are shown to be practical models for high-power laser drivers since most light beams can be described with the use of partially coherent beams [18] .…”
