Abstract
In order to optimize the design of a fiber Raman laser, a numerical model is adopted for a cascaded Raman fiber laser, and a new numerical algorithm is described including Runge-Kutta and the least squares methods that can be applied to cascaded Raman fiber lasers.The effects of output reflectivity, fiber length and pump power on the output characteristics of the cascaded Raman fiber laser are studied in detail. The results show that the algorithm makes the model robust and fast and the simulation results are in good agreement with experiments.
