Raman Fiber Amplifiers for Amplification of Single Frequency Narrowband Signals

1053/526nm, 1064/532nm, 1120/560nm, 1140/570nm, 1160/580nm, 1166/583nm, 1178/589nm, 1185/592nm, 1212/606nm, 1240/620nm, 1256/628nm, 1284/642nm, 1294/647nm, 1340/670nm.Custom wavelengths also available.

MPBC’s Raman Fiber Amplifier System is capable of amplifying a narrow, linearly-polarized, near-IR input signal without spectrum broadening. NIR output powers of up to 8 Watts at wavelengths between 1030nm and 1340nm 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 near-IR signal into the visible region using our Second Harmonic Generator. Output power up to 2 Watts are available for various wavelengths in the visible region.

Raman Fiber Amplifiers

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
  • Optional Second Harmonic Generator: Converts the frequency of the amplified signal to the visible spectrum with high efficiency

Features

  • True diffraction limited beam with M2 < 1.1
  • Unprecedented beam pointing and power stability
  • All-fusion-spliced fiber-optic train eliminates the need for alignment
  • Maintenance-free turn-key operation
  • Low power consumption compact package

Applications

  • Laser Guide Star for Adaptive Optics
  • Sodium Vapor Spectroscopy
  • Atom Cooling
  • Microscopy
  • Interferometry
  • Holography
  • Bio Photonics Applications
