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.
