Abstract

We present an analytical solution for a radiation balanced fiber laser, in which no net heat is generated during lasing operation due to cooling by anti-Stokes fluorescence. The results are in excellent agreement with the numerical solutions. Using realistic values for fiber laser parameters, the analytical solutions presented are proposed as an economically desirable alternative to time-consuming, direct numerical calculations.
