Narrow-Band
Visible Raman Fiber Amplifier System

MPBC’s Visible Raman Fiber Amplifier System is capable of amplifying a narrow, polarized, near-IR input signal without spectrum broadening and converting it to the visible region.

Visible output powers of several watts at wavelengths between 560 nm and 650 nm are achievable, with custom wavelengths available based on demand.

The VRFA System consists of three modules:
