SF Raman Fiber Amplifiers

Raman Fiber Amplifiers (RFA-SF Series) can provide optical gain in spectral bands not covered by rare-earth amplifiers. They are designed to provide high output power for narrowband single-frequency sources. The Visible Raman Fiber Amplifiers (VRFA-SF Series) includes an SHG module which converts the IR emission into the visible.

Designed to amplify single-frequency signals without triggering SBS
Large variation of wavelengths
High output power
Diffraction-limited fiber or collimated beam output
