| Abstract: | Analyzing backwardly pumped Raman fiber amplifier is a problem of solving two-boundary ordinary differential equations in mathematics. Traditional shooting method with equal and varying steps is not efficient. Based on the mathematical model of Raman fiber amplifier, a novel step predicting method was proposed and mathematical expressions were given. The novel algorithm leads to quicker convergence and higher accuracy. It can save 60% of time in comparison with the general methods with the same accuracy. |
