Theoretical Study for Neodymium-Doped Optical Fiber Laser

Abstract

In this paper, as the first the rate equation for a four-level system in end-pumped fiber laser have been solved analytically with minimum approximation and the lasing output power versus pump power has been derived. The results were applied by a numerical solution for Nd³⁺ doped fiber laser.

Keywords: Neodymium, rate equations, silica glass, ZBLAN glass.
