SM-TDF-10P/130-M, Matched Tm-Doped Double Clad Optical Fiber

Product image of SM-TDF-10P/130-M, Matched Tm-Doped Double Clad Optical Fiber

Coherent thulium-doped double clad fibers utilize glass compositions specifically optimized for high cross-relaxation rates between Tm ions, enabling efficient conversion of 793 nm pump photons into signal photons at 2 µm. The precision matched -M fiber version offers higher absorption and efficiency than the -HE version. The waveguide design in the -M version is tailored for single-mode operation in monolithic fiber laser/amplifier systems when spliced to precision-matched passive fibers. These fibers, along with matching passive fibers, are available in a 130 µm cladding diameter for ease of handling, cleaving, and splicing, enabling reliable manufacturing of low-power, eye-safe fiber lasers and amplifiers.

Features

  • Optimized core composition - High efficiencies when pumped at 793 nm
  • Optimized waveguide design - Truly single-mode operation
  • High absorption - Useful for generating high peak powers
  • NuCOAT fluoroacrylate coating - Greater fiber durability in extreme operating and storage conditions
  • Proof tested to > 100 kpsi - Ensures long-term reliability when coiling
  • RoHS compliant

Applications

  • Low to mid-power CW and pulsed lasers & amplifiers at 2 µm
  • Eye-safe industrial & medical lasers
  • Military and commercial LIDAR
  • Pumping of Ho-doped lasers & amplifiers
