Optical Isolator for Fiber Laser
We have commercialized high-power isolators and polarizers for fiber lasers.
They can be used with Yb and Er fiber lasers in the 1064nm and 1550nm bands.
Our product suppresses various unstable operations such as laser output fluctuations, frequency variations, modulation band suppression, and LD destruction.
As an indispensable device for laser stabilization, please use the isolator from Shinko.
