LIEKKI® Passive-25/250 (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
    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
