| Abstract: | The gain of a Raman amplifier with single pump was worked out based on the differential equations describing the dependence of the number of pump photons and Stokes beam photons on the distance; The resulting equations for multi-pumping and multi-channel were resolved numerically without neglect and were compared with the experimental results in other papers; The wavelengths and powers of the pumps were optimized by using genetic algorithm to realize the gain flattening when using multi-wavelength pumping. |
