Product details
Overview
The FT-1040-5 shields 1040 nm polarization-maintaining fiber lasers and amplifiers from destabilizing back reflections. It ships in 10 W and 20 W continuous-wave classes and also tolerates high peak powers from nanosecond pulses, a match for ultra-fast laser sources. The PM path holds extinction ratio steady in the forward direction while reverse isolation stays high. Insertion loss is kept low and return loss strong, so the signal path remains clean. It fits ultra-fast fiber laser systems, test benches and PM-fiber sensor setups. Full parameter values are listed in the specification table.
