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

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. 

Description

This fiber features a confined core for selective gain amplification in basic mode and depressed-gain cladding for enhanced 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 core glass host
  • Birefringent fiber
  • Confined core for selective gain amplification

Applications

  • Material processing
  • Frequency conversion
  • Range finding
  • Biophotonics
