MPBC’s Raman Fiber Amplifier System is capable of amplifying a narrow, polarized, NIR input signal without spectrum broadening.

In addition, MPBC offers the option of converting the NIR signal into the visible region.

NIR output powers of up to 8 Watts can be achieved with MPBC’s air-cooled platform, and a water-cooled option is available for even higher power for specific wavelengths.

If visible output is required, MPBC single-pass SHG can handle output powers of up to 2 Watts.

The VRFA System consists of three modules:

Raman Fiber Amplifier: Based on single-mode polarization-maintaining fiber, the RFA accepts the seed signal, amplifies it without spectrum broadening, and outputs it to the Second Harmonic Generator
Ytterbium Fiber Laser: Pumps the Raman Fiber Amplifier with high-intensity linearly polarized emission needed for the amplification
Second Harmonic Generator: Doubles the output wavelength to the visible spectrum

Features

Amplifies narrowband (< 5 MHz) linearly-polarized signals and frequency
doubles into the visible band without spectrum broadening
All-fusion-spliced optical train eliminates the need for alignment
Unprecedented stability
Air-cooled
Compact
Easy to Use
