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
