Technical Datasheet Note
Custom fiber types, core diameters and connector terminations confirmed during Engineering Review. Handling power depends on fiber core size and cooling setup.
Configuration and ordering notes

Designed specifically for multimode pump and laser protection where standard single-mode isolators cannot be used. Configuration parameters include fiber type matching the pump-diode pigtail during configuration review.

Selection Guidance: Compare combiner architectures and fiber matching in our Pump Combiner Selection Guide ↗ or N×1 vs (6+1)×1 Architecture Guide ↗.

Key Applications

Multimode pump protection; Fiber laser oscillator & amplifier systems; Laser material processing; Industrial photonics.
