Abstract

In order to study the dependence of output characteristics on the parameter of multi-order cascaded Raman fiber lasers,the nonlinear coupled equations,describing modeling of multi-order cascaded Raman fiber lasers,were solved.Based on numerical simulation,the effect of fiber length,reflectivity of output coupler and pump power on the output characteristics of a 6-order cascaded Raman fiber laser was obtained.The results showed that the Raman fiber lasers had lower threshold power and could obtain the maximum output power when the fiber length was about 300m,and the reflectivity of the output mirror was about 10%.
