Abstract
Under certain conditions,the optimum fiber length of erbium-doped fiber laser,and laser optimum reflectivity of the two mirrors,the output characteristics of fiber laser designs can be optimized. Based on the rate equations applicable to the erbium-doped fiber laser,a continuous erbium-doped fiber laser of linear cavity has been studied,and analytical expressions on laser output power,threshold pump power and siope dfficiency under stationary condition have been derived.The pump power is 20MW,bait ion doping concentration is 400 ppm,fiber length is 1.5m, R1 is 1,R2 is 0.5,the output characteristics can obtain ideal. To provide theoretical basis for the optimization design of optical fiber laser.关键词
