Description
The 1.0µm High Power Chirped Fiber Bragg Grating (FBG) from Connet is a high-performance optical reflector designed for use in advanced fiber laser systems. Written into specialty double-clad fibers using precision chirped grating technology, this chirped fiber Bragg grating is engineered for both continuous wave and pulsed high-power lasers operating around the 1µm wavelength range. Offering excellent thermal stability, high reflectivity, and exceptional mode control, this 1um FBG serves as a reliable cavity mirror in both single-mode and large mode area (LMA) fiber configurations. With pump and signal handling capabilities up to 3000W, this grating is available in recoated or heat-dissipative metal packages to suit diverse deployment needs.
Whether you require broadband reflectivity or matched low/high reflector pairs, Connet’s solution offers customization across wavelength, bandwidth, and fiber type, making it ideal for OEMs and integrators in industrial laser manufacturing.
Connet can provide various bandwidths and accurately matched high and low reflectivity gratings for different applications. They are offered in heat dissipative package or recoated only.
