2000nm High Power Pump and Signal Combiners

These pump and signal combiners can be used for high power fiber lasers and fiber amplifiers specially designed for use at the 2000nm wavelength. They can be used to combine several pump lasers and couple that power with a seed signal.

Features

  • High Power
  • Low Excess Loss
  • High Directivity
  • Stable and Reliable

Applications

  • Laser Positioning
  • High Power Fiber Lasers
