Abstract :
This letter presents the design of a dual-order Raman fiber laser to be used as a pump for distributed Raman amplification. In particular, noise figure, gain ripple, and tunability are measured and analyzed in comparison to first-order Raman amplification. The tradeoff between noise figure improvement and increased nonlinear penalty is also discussed.
