AFR ClearCutâ„¢ Raman Scattering Suppression Fiber Bragg Grating (RSS-FBG) for Continuous Wave Laser | |
12 May 2021 Raman Scattering in fiber is a nonlinear process that converts some of the photons at fiber laser wavelength to photons at relatively longer wavelength. The higher the laser power the stronger the Raman Scattering. It must be controlled in a high-power fiber laser, or it would severely limit the laser performance. AFR ClearCut™ RSS-FBG is designed by a special Fiber Bragg Grating written onto a high-power fiber that is transparent to the laser wavelength while suppressing the unwanted Raman Scattering wavelength. It can be applied either right after a fiber oscillator or before a fiber amplifier to assure laser output of improved spectrum purity. The product is rated for 3000 Watts and has little loss at laser wavelength while filtering out the unwanted Raman shifted wavelength. The filter-out power can be as high as 30 Watts, which is dissipated through the metal housing of the product. The product produces little backward reflection to the laser oscillator or the amplifier. The standard specifications of ClearCut™ RSS-FBG:
