Fiber End Cap-003

Description

Fiber End-Cap is designed for the output termination of high power fiber lasers and fiber amplifiers in order to reduce the power density at the output fiber facet. A Y mm-diameter and X mm-long quartz rod is fused to the fiber facet for beam expansion while preserving minimal beam distortion. A Cladding Light Stripper is built inside in order to remove the reflection power in the fiber inner cladding.

Key Features

  • High Signal Transfer Efficiency
  • Built-in Cladding Light Stripper
  • Low Beam Distortion
  • Customized Configurations Available
