ramanverstu00e4rker and method for stimulating a ramanverstu00e4rkers

摘要

The amplifier has a pump laser module (16) with a frequency discriminator (24) that selects an optical frequency. The selected frequency is spaced apart from a local maximum in optical power of remaining frequencies. The optical frequencies are one stokes-frequency above the signal frequency range. A pump laser module (18) emits an optical frequency, one stoke-frequency apart from the frequency of the local maximum. An independent claim is also included for a method of pumping a Raman amplifier.
