SNx1 signal combiners 

These devices are designed to combine several high-power fiber laser sources into one fiber with total power of 10 kW or more. The structure is similar to the Nx1 pump combiners. The difference is that each fiber is a signal fiber.

 

Signal combiners are produced in structures:

  • 7х1
  • 4х1


Main features:

  • High transmission efficiency
  • Insensitivity to different wavelengths
  • High power transmission (up to 1800 W per port)
  • High output power (up to 7700 W)
  • Wide temperature range of operation and storage
  • Shells with an efficient heat dissipation and water cooling
