A simple high-efficiency forward-pumped Raman fiber laser
In this work, we present a novel simple architecture of a high-efficiency forward-pumped Raman fiber laser based on efficient seeding of the Stokes wavelengths through a passive pump combiner. We demonstrate 52 W of power in 1480 nm band for a pump power of 109 W with high spectral purity.
