Raman Fibre Amplifiers

MPBC’s Raman Fiber Amplifier System is capable of amplifying a narrow, linearly-polarized, NIR input signal with minimum spectrum broadening.

NIR output powers of up to 15 Watts at wavelengths between 1030 nm and 1342 nm can be achieved in our standard air-cooled enclosure, with higher power available upon demand with our water-cooled enclosure.


In addition, MPBC offers the option of converting the NIR signal into the visible region using our Second Harmonic Generator.

Visible power up to 2 W is achievable for various wavelengths, some examples include:
























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 SF System consists of three modules:


  • Raman Fiber Amplifier: Based on single-mode polarization-maintaining fiber, the RFA accepts a narrowband seed signal and amplifies it to a high power with minimum spectrum broadening
  • Ytterbium Fiber Laser: Provides a high-intensity linearly polarized pump light needed for Raman Amplification
  • Second Harmonic Generator (Optional): Converts the frequency of the amplified signal to the visible spectrum with high efficiency
