WebMay 1, 2024 · In this paper, a laser beam from a fiber coupled diode laser source is converted from a Gaussian-like distribution to a flat-top distribution using a set of … WebHere, we studied the superposition of a zero-radial-index LG beam and an off-axis Gaussian beam with its center at the point ( a, 0) (in the Cartesian coordinates) in the waist plane. The waist radii w0 of both beams were supposed to be equal. Without loss of generality, we also supposed that a > 0.
