Fiber End Cap

Fiber End-Cap is designed for output termination of high power fiber laser and fiber amplifier to reduce the power density at 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
