In this paper, as the first the rate equations in end pumped fiber laser have been solved analytically with minimum approximation and the output power versus input power has been derived. Then, the heat conduction equation in the fiber which is in operation has been solved and the temperature distribution has been derived. The results were applied for a Yb doped fiber laser and discussed.
