Novel method to optimize the distributed pump powers in a kilowatt ytterbium-doped double-clad fiber laser

Abstract:

The rate equations with multipoint boundary conditions are solved by numerical method accurately. A novel method based on genetic algorithm is proposed to optimize distributed pump powers in kilowatt YDDC fiber laser in this paper. The calculated results show that lower operation temperature and better uniformity can be achieved through an optimized pump arrangement.
