Design of Yb Fiber Gigh Power Amplifier Through 915nm Pumping

摘要

By analyzing the fiber amplified theory, we obtain the transmission formula of pump and signal for the use of rate e-quation. In the experiment, take the Yb-doped double cladding fiber based on phosphor silicate as gain medium, high power single emitter in 915nm as pump source. According to gain fiber length obtained by the theory analyses, the output power achieves above 20W.
