GenX Precision Matched Active

LMA Double Clad Fiber

GenX fibers are the newest series of Large Mode Area (LMA) double-clad fibers, specifically tailored to enable power

scaling of multi-kW -class fiber lasers and amplifiers. Offering superior photo-darkening (PD) performances with maintained

and/or higher absorption, these fibers are optimized to benefit both CW and pulsed multi-kW systems. The 14/250 GenX

design is ideal for efficient and reliable kW-class systems. The 20/400 GenX offers the same absorption with significantly

lower PD than comparable products providing an optimized platform for high efficiency and high-reliability multi-kW CW

lasers. The 25/250 GenX product combines higher absorption and superior PD, ideal for enabling multi-kW peak power

scaling with reduced cavity length and nonlinearities.

 

Typical Applications

• kW Class Fiber Lasers & Amplifiers

• Materials Processing

• Military, Industrial and Medical

Features & Benefits

• Superior photo-darkening performance in both CW and pulsed applications

• Enhanced reliability for power scaling beyond kW level

• Higher absorption mitigates non-linearities and enables higher peak powers

• NuCOAT-FA-HP – for enhanced coating reliability in industrial environments

• Designed to work with existing matched passive fibers
