Yb-MCOF-35/250-07-0.9-PM

Fibre optique spéciale

The Yb-MCOF-35/250-07-0.9-PM is a multi-clad, PM fiber with a core diameter of 35 µm, designed for M² lower than 1.15. Our fiber features a confined core for selective gain amplification and multi-layer cladding for superior suppression of higher order modes, making it perfectly suited for amplifying narrow linewidth seed lasers operated in pulsed mode and for applications requiring superior beam quality.

 

Features:

  • Low photodarkening
  • High birefringence
  • Confined core for selective gain amplification

Applications:

  • Material processing
  • Frequency conversion
  • Biophotonics
  • Range finding
