Product Detail
The ClearCut Raman Scattering Suppressor Fiber Bragg Grating (RSS-FBG) products are ultra low insertion loss fiber bragg gratings for high power fiber lasers. With AFR's ClearCut designing and special process, the devices can handle kilowatt level pump power and signal power with recoated only. It is the only cost-effective solution that eliminates the SRS at its source and enables immunity from back reflection from the work piece.
