摘要：

The gain-guided nature of an amplifier can lead to more noise in the output than would be predicted based on the quantum noise limit of one photon per mode. We report the results of an experiment which demonstrate that the gain-guided nature of a focused-gain Raman amplifier can lead to excess noise in the amplified field. The results are compared with a theoretical analysis of the output of an amplifier which incorporates the effects of gain guiding as well as the focused nature of the gain profile.
