High absorption single clad Yb-doped PM-fiber

YB250-6-PM

Description

A highly absorbing, polarization-maintaining (PM), Yb-doped single-clad fiber with a small mode field diameter is well- suited for applications that demand efficient pump light absorption within a compact length and stable polarization control.

Features & Benefits

  • Efficient pump absorption over compact length
  • Single-clad structure for core pumping
  • Low risk of lasing or parasitic amplification
  • Stable linear polarization for sensitive optical systems
  • Minimizes nonlinear effects and thermal load
  • Compact integration in fiber-based setups

Applications

  • Polarized ASE sources
  • Interferometry
  • Pump dump in mode-locked or ultrafast PM laser cavities
  • Broadband polarized light sources for sensing and metrology
  • Optical load / termination in PM systems
  • Fiber optic gyroscopes
