| In this paper, the temperature distribution in fiber lasers pumped by multi diode bars located in out of fiber axis has been investigated semi analytically. For this reason, we consider heat deposition in fiber lasers due to pump and the nonhomogeneous heat conduction equation has been solved by using Green function method in a cylindrical coordinate system. Our model has been used for single, double and multi pumped configuration and, for a typical fiber lasers, the results have been plotted and discussed. |
