Laser beam shaping using a single-mode fiber abrupt taper.
A new beam-shaping device was realized by an abrupt taper with a length of approximately 700 microm and a waist of approximately 40 microm. The insertion loss of the device is less than 3%. The diameter of the flat beam top can be up to approximately 900 microm with a small intensity variation (4%) and a small half-divergence angle (2.5 degrees). The conversion efficiency of the new device from...
متن کاملOptical Design of Laser Beam Shaping Systems
An overview of the history and current practices of laser beam shaping is presented. When diffraction effects are not important, geometrical methods for laser beam shaping (ray tracing, conservation of energy within a bundle of rays, and the constant optical path length condition) can be used to determine system configurations, including aspheric elements and spherical-surface GRIN lenses, whic...
متن کاملInvestigation of Thermal Dispersion and Thermally-Induced Birefringence on High-Power Double Clad Yb:Glass Fiber Laser
In this work the effects of heat generation on the modes of Yb:Glass double clad fiber laser were investigated. The thermal dispersion and thermally-induced birefringence were considered when the gain medium becomes an anisotropic medium. The results showed considerable modifications of laser modes profiles, in particular for transfer magnetic (TM) and transfer electric (TE) modes which their p...
متن کاملAnalytical Beam Shaping with Application to Laser Diode Arrays
In contrast to numerical methods for beam shaping, analytical beam shaping consists of two steps: rst, nding a purely geometrical distortion between the input and output plane redistributing the intensity of the incoming wavefront and second, computing a phase-only element realizing this coordinate transform. For the latter the method of stationary phase may be applied. The known classes of pos...
متن کاملApplication of genetic algorithm on optimization of laser beam shaping.
This study proposes a newly developed optimization method for an aspherical lens system employed in a refractive laser beam shaping system, which performs transformations on laser spots such that they are transformed into flat-tops of any size. In this paper, a genetic algorithm (GA) with multipoint search is proposed as the optimization method, together with macro language in optical simulatio...
