Study on the Threshold in Ytterbium-Doped Fiber
On the basis of the population rate equation, energy levels and spectrum characteristics of Yb3+ in host and McCumber relation, the formulas describing pump threshold power are deduced for Yb3+-doped fiber laser. The factors affecting pump threshold power are analysed. Related experiments have been conducted. Theory are in accord with experimental results.
