LIEKKI® Yb1200-12/125DC (-PM)(-HELMI)

LIEKKI® Yb1200-12/125DC(-PM)(-HELMI) fibers are highly doped large mode area fibers for medium power fiber laser and amplifier applications, where high beam quality and compact design are essential. Now also available with latest core design LIEKKI® HELMI* for increased photodarkening resistant.

*Contact nLIGHT to learn more about LIEKKI® HELMI (High Energy Laser Material Improvement) benefits.

Features

• Direct Nanoparticle Deposition: Industry leading fiber deposition process 

• LIEKKI® HELMI: New core design with up to 75% lower photodarkening

• realNA: most accurate fiber core NA to enable superior predictability of fiber performance and minimal splice loss 

• Performance:
  Optimized for stable beam quality in a large core fiber design.

  LIEKKI® HELMI fiber version offered with 0.07NA core for increased mode field diameter and more robust single-mode operation.

• Reliability: Double cladding fiber coating proven to operate up to 150˚C and in extreme humidity

• Compatibility: nLIGHT passive fibers matched for minimal splice loss 

Applications

•  Medium power cladding pumped fiber lasers and pre-amplifiers

• Pulsed and CW applications in industrial, medical and scientific markets

• IR sources for frequency doubling
