Design of fiber-laser arrays with genetic algorithms

摘要

The optimization of the far-field pattern of fiber-laser arrays is investigated based on genetic algorithms. A derived objective function of the far-field pattern performs the task of evaluating each of the fiber-laser designs generated by the genetic algorithm. The constrained parameters of the design included are radius of the fiber a, the important V value, the fiber-to-fiber separation S, and the operational wavelength λ. As results, sidelobe level is optimized to be -38.83 dB for a circular arrays with the given constrained parameters.
