20/400 Precision Matched Active LMA Double Clad Fiber
The Large Mode Area (LMA) double clad fibers are ideal for high power monolithic fiber lasers and amplifiers. This matched fiber series is based on a 20 micron diameter core and 400 micron diameter clad size with a low NA (0.065) core and consists of Yb-doped fiber and passive beam delivery fibers all made to the highest tolerances in the industry. This fiber utilizes Gen 8 glass composition to ensure excellent preservation of beam quality. The new NuCOATFA-HP high performance coating technology extends the operating life at the higher power levels demanded by today's industrial fiber laser applications.
