LMA-GDF-30/400, Passive Double Clad Optical Fiber
Coherent passive series of Large Mode Area (LMA) double clad fibers are ideal for high power monolithic fiber lasers and amplifiers. These passive fibers are based on a 30 micron diameter core and 400 micron diameter clad size with a low NA (0.06) core and are designed to work well with the active Yb-doped 30/400 LMA fibers. These fibers utilize the latest fiber design and NuCOAT fluoroacrylate coating technology to ensure excellent preservation of beam quality and extended operating life at the high power levels demanded by today’s industrial fiber laser applications. These fibers are available in both non-PM and PANDA-style PM fibers.
Features
- Designed for compatibility with 30/400 active fibers
- NuCOAT fluoroacrylate coating - Greater fiber durability in extreme environmental operating & storage conditions
- Optimized LMA core design - Easy to maintain single mode LP01 beam through fiber & components at high power
- All fiber proof tested to > 100 kpsi - Critical for ensuring long term reliability when coiling
- RoHS compliant
Applications
- Monolithic high power lasers & amplifiers
- LMA fiber couplers & pump combiners
- High power pump & signal pigtails
- Military
- Industrial and medical
