The new IO-K model is the newest of the polarization-independent fiber

isolators. It couples high-powered fiber coupling experience with all of OFR°O

high-power, free-space isolator experience to produce the highest power, fiber

coupled isolators available. The fiber laser market is experiencing tremendous

advances in power handling requirements, and we are continually working with

new fibers and technologies to accommodate these new challenging power

levels. The IO-K uses new fiber technologies and thermal management

techniques to push the damage thresholds to new levels. See the website for

models as they develop.
