Configuration and ordering notes
This series covers power levels between low-power isolators and larger high-power packages. Stage count and isolation are reviewed for the intended configuration.
Selection Guidance: Review thermal dissipation, damage thresholds and cooling options in our High Power Optical Isolator Guide ↗ or compare operating bands in the 1064nm and 1550nm Optical Isolator Selection.
Key Applications
Fiber amplifiers; MOPA fiber lasers; Seed laser isolation; Industrial marking laser pre-amplifiers.
