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.
