Design of fiber-laser arrays with genetic algorithms

The optimization of the far-field pattern of fiber-laser arrays is investig ated based on genetic algorithms. A derived objective function of the far-f ield pattern performs the task of evaluating each of the fiber-laser design s generated by the genetic algorithm. The constrained parameters of the des ign included are radius of the fiber a, the important V value, the fiber-to -fiber separation S, and the operational wavelength lambda. As results, sid elobe level is optimized to be -38.83 dB for a circular arrays with the giv en constrained parameters.
