TOP® Multicore Fiber

TOP® multicore fibers open new capabilities for laser power delivery: by using different cores, or several cores at once, power density and beam shape can be precisely controlled. TOPRAYS offers customizable multicore fibers to meet your specific needs.

Advantages

Supports kilowatt-level power

Non-circular core shapes possible

Precise control of power density

Higher precision

Step-index profile

Special jackets available for high-temperature, high-vacuum and highly corrosive chemical environments
