400 Micron Core Power Delivery Fibers

Product catalog summary
Overview: Nufern's specialty multimode step-index fibers are designed for compatibility with most fiber-coupled, bar, and stack diode-laser packages, supporting the diode laser power delivery market. These fibers are available in 400/440 and 400/480 core/clad ratios with low and high Numerical Aperture (NA) versions.
Typical Applications:
  • Fiber coupled diode lasers
  • Couplers and pump combiners
Features & Benefits:
  • Available in 0.12 and 0.22 NA, making them compatible with most fiber-coupled, diode-laser packages.
  • Exceptional geometric uniformity and core/clad concentricity facilitate ease of coupling to pump diodes.
