Product Description

105 & 106.5 Micron Core

Power Delivery Fibers

Nufern's specialty multimode step-index fibers are designed for compatibility with the majority of fiber-coupled, single

emitter, diode-laser packages and support the diode laser power delivery market. These power delivery fibers are

available in a 105/125 core/clad ratio in low and high NA versions and also in a 106.5/125 core/clad ratio with high NA.

The 106.5/125 fiber features high temperature acrylate as a standard coating in order to meet the challenges of harsh

environments and high pump powers demanded by today’s need for robust applications. Other fiber diameters and coatings

are available upon request.

Typical Applications

• Fiber coupled diode lasers

• Couplers and pump combiners

Features & Benefits

• 0.12, 0.15 and 0.22 NA — Compatible with majority of fiber-coupled, diode-laser packages

• Exceptional geometric uniformity and core/clad concentricity — Ease of coupling to pump diodes
