Paper Abstract

With cascade oscillation scheme from level 5I6,to 5I7, to 5I8 in Ho3+: ZBLAN fiber laser, it not only can produce cW 3- and 2- ?m laser beams simultaneously from one oscillator with appropriate pumping source, but also improves the output power and efficiency. In this paper, the operation principles of 3- and 2- ?m cascade Ho3+: ZBLAN fiber laser is analyzed. Both dynamic and steady state rate equations of this laser pumped with1.1-?m band laser are given for the first time. Basic designs of this laser pumped by Ytterbium-doped double clad fiber lasers (YDCFL) are given. Based on the theoretical analysis and designs, numerical computations of the steady state rate equations were performed. The numerical solutions agree well with the experimental results.
