Abstract
Proposed is a beam shaper for beams emitted from at least one laser-diode bar and consisting of a fast-axis collimator composed of a common cylindrical lens with an aspherical profile, an array of spherical/aspherical telescope units formed from a pair of microlenses, where each individual telescope unit is shifted in accordance with a predetermined law to a certain distance relative to a neighboring individual telescope unit, an array of cylindrical lenses shifted relative to each other in accordance with another predetermined law, and a system of collimation lenses that collimate the beams of the predetermined spatial pattern into a two-dimensional pattern having a less discrete and more uniform distribution of light intensity and a shape more convenient for subsequent coupling, e.g., for focusing into the end face of an optical fiber of a light transmission system.
