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.

What are the typical central wavelengths supported?

Supported central wavelengths include 1018nm, 1050nm, 1064nm, 1070nm, 1080nm, and 1090nm, with a tolerance of ±1nm.

Can I request a custom grating specification?

Yes. Connet provides customization on central wavelength, reflectivity, bandwidth, and fiber type upon request.

What is the power handling capacity of this chirped fiber Bragg grating?

Depending on the fiber type and packaging, the FBG can handle pump powers up to 3000W and signal powers up to 2000W.

What fiber types are supported?

Fiber types include 10/125, 15/130, 20/130, 30/250, 20/400, 25/400, among others, covering both SM and LMA fibers.

What packaging options are available?

The product is available in recoated fiber form or high-power heat-dissipating metal housings, suitable for integration in harsh environments.

How does the chirped FBG differ from uniform FBGs?

Chirped FBGs have a varying grating period that allows for dispersion management and pulse shaping, which is essential in ultrafast laser applications.
