Abstract
A comparison of the theoretical predictions of a multimode broadband model with the experimentally measured gain enhancement in a Raman amplifier is presented. The results show that the multimode theory with fixed and totally random phases is in agreement with the data obtained from an excimer-laser-pumped Raman amplifier. Additionally, this theory indicates that the correlated gain can be larger than the gain for a monochromatic laser, as might be expected for a model with amplitude modulation.
