PurePath TG-CPS(RSS Series)
The PurePath TG-CPS combines the functions of an Output Coupler FBG (OC-FBG), a Raman Scattering Suppressor FBG (RSS-FBG), and a Cladding Power Stripper (CPS). This device can handle 3 kW of signal power with low insertion loss. The CPS is designed for efficiently stripping off residual cladding power, ASE and escaped core modes of double cladding fiber while preserving minimal degradation to signal power and beam quality.

Refractive-Index Change [SabRay-FBG飞秒光纤光栅加工系统.pdf Page 1 Independent Introduction; Quartz Glass]: ≥0.45 Low-Scattering FBG Spot Diameter [Independent Page 1 Introduction in SabRay-FBG飞秒光纤光栅加工系统.pdf]: ≤150 nm
The SabRay-FBG femtosecond fiber-grating processing system uses advanced beam shaping to induce high refractive-index modulation inside transparent media, with index change ≥0.45 in quartz glass, and low-scattering FBG points ≤150nm in diameter. It produces FBG waveguides and fiber gratings described as having the highest contrast to date. Inheriting all SabRay advantages, its granite gantry provides processing stability, while a highly accurate, long-travel motion platform supports large-area ultrafine processing.
