LIEKKI® Passive-20/400 (DC,-PM)

LIEKKI® passive fibers are especially designed and manufactured to match the optical guiding properties of LIEKKI® large mode area Ytterbium doped fibers. This enables optimal mode coupling with minimal splice loss for maintaining the power and excellent beam quality between all elements of a fiber laser or amplifier. High-quality Fiber Bragg Gratings can be written into all LIEKKI® passive fibers. 

Features

• Compatibility:
  realNA — most accurate fiber core NA for minimal splice loss
  Core design and guiding properties matched to Yb-doped fiber
  Glass cladding diameter is designed to “fit-in” octagonal active fibers
  Fiber Bragg Gratings can be written into all large mode area passive fibers

• Reliability:
  Single cladding fibers feature a telecom grade dual layer high-index acrylate coating
  Double cladding fiber coating proven to operate up to 150˚C and in extreme humidity

Applications

• Fiber-based components for fiber lasers (e.g. pump combiners; FBGs)

• Pigtails for fiber lasers and amplifiers

• All-fiber subassemblies
