Abstract

An approximate explicit solution for Raman fiber lasers with arbitrary cascades is obtained. The solution is deduced without using depleted pump approximation. The proposed analytical solution shows excellent agreement with numerical simulation. Furthermore, optimal design of the cascaded Raman fiber lasers is carried out analytically. The optimal values of fiber length, reflectivity of output fiber Bragg grating and power conversion efficiency are obtained under different pump power. The optimal fiber length and reflectivity of output FBG decrease with increasing pump power. There exists a certain tolerance of the optimal cavity parameters, in which the conversion efficiency decreases only slightly. In addition, by the proposed solution one can readily determine whether pump power is depleted.
