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.
