High Power Single Frequency Raman Fiber Amplifiers
MPBC’s Raman Fiber Amplifier System is capable of amplifying a narrow-band, linearly-polarized NIR input signal with negligible spectral broadening, and low intensity and phase noise. NIR output powers up to 15 Watts at wavelengths between 1030 nm and 1370 nm can be achieved in our standard air-cooled enclosure, with higher powers available upon demand with our water-cooled enclosure.
In addition, MPBC offers the option of converting the amplified NIR signal into the visible region using our Second Harmonic Generator. Visible powers up to 4 W areachievable for various wavelengths.
The SF System consists of three modules:
- Raman Fiber Amplifier: Based on single-mode polarization-maintaining fiber, the RFA accepts a narrow-band seed signal and amplifies it to high power with negligible spectral broadening
- Ytterbium Fiber Laser: Provides high-intensity linearly-polarized pump light needed for Raman amplification
- Second Harmonic Generator (Optional): Converts the frequency of the amplified NIR signal to the visible region with high efficiency
