LMA Tm doped fiber

DCF-TM-25/400P-12

Description

Specifications
Specifications

OurLMA 25/400 fiber with a pedestal structure operates across the 1.9 μm to 2.1 μm wavelenght band. Its 25 μm core diameter helps reduce nonlinear effects, making it well-suited for high-power applications. Additionally, the 400 μm cladding enables pump absorption for scalable power output.

Features & Benefits

  • Octagonal claddingshape
  • High pump and consistent absorption
  • Proof tested to >100kpsi for ensuring long term reliability when coiling

Applications

  • Medical
  • Material processing
  • LIDAR (defense and commercial)
  • High power CW and pulsed applications
  • Pump of ho-doped fibers
  • Research
