Diffraction grating
COHERENT
Holographically recorded phase masks are high-precision phase diffraction gratings, intended for use in the fabrication of fiber Bragg gratings (FBGs).
Coherent is an independent designer and manufacturer of specialty optical fiber, phase masks and advanced optical components. Our specialty fiber and phase masks are used in a wide range of industries and applications, including optical telecommunications, fiber lasers, fiber optic gyroscopes, and fiber sensors.
Our holographically recorded phase masks are high-precision phase diffraction gratings, intended for use in the fabrication of fiber Bragg gratings (FBGs). Coherent was a co-developer of the world's first phase mask for FBG fabrication. FBGs serve as in-fiber wavelength filters in a variety of applications, including telecommunications (WDM and gain-flattening), fiber lasers, and pressure, strain and temperature sensors.
