Single Frequency Fiber Amplifiers and Fiber Lasers

MPBC’s Single Frequency Fiber Lasers and Amplifiers provide low phase and intensity noise, narrow spectral  linewidths and long coherence lengths.  These characteristics make them ideally suited for demanding applications which include atom cooling and trapping, artificial laser guide star, holography, interferometry, LIDAR, metrology and remote sensing.

MPBC’s Raman Fiber Amplifier System is a high power single frequency amplifier capable of accepting the output of a narrow-band single frequency seed source  and amplifying from milliwatts to several watts in the NIR.  The output of the Raman Fiber Amplifier can then be frequency doubled by a Second Harmonic Generator to provide stable, narrow linewidth, low noise visible output.  

MPBC’s Single Frequency Fiber Laser System is a complete self-contained system offering a true single frequency output beam with out mode-hops.  The NIR or Visible SF laser is provided in a compact, air-cooled package requiring a minimum of effort to set up, operate and maintain

Single Frequency Raman Fiber 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.

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

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
