DCF-YB-6/128S-PM

Description

The DCF-YB-6/128S-PM offers excellent photodarkening resistance performance ensuring high reliability and long-term stability. This PM fiber is designed for single-mode operation and shows high absorption and high birefringence, which are ideal for the design of ultrafast or frequency-doubled fiber lasers.

Features and Benefits
  • Single-mode operation for excellent beam quality
  • Very low photodarkening at high power – ensures stable long-term operation
  • High birefringence – minimizes stress
  • High efficiency – reduces pump power requirements
Applications
  • Ultrafast pulsed fiber lasers
  • Pulsed lasers and amplifiers
  • Material processing
  • Second Harmonic Generation
  • Scientific
