Design of Yb Fiber High Power Amplifier through 915nm Pumping
Analyze the fiber amplified theory and obtain the transmission formula of pump and signal for the use of rate equation. 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 20W above. Apply the cladding power stripper at the output end for stripping the remained pump power.
