T90 / Fiber Laser Matched FBG Pairs



The T90 is a Fiber Bragg Grating (FBG) Array consisting of two FBGs written and matched as a pair into specialized fibers that are used for High-Power and Ultra-Fast Fiber Laser applications. Available in a wide range of specifications, the FBG pairs are naturally packaged directly in bare fiber and are designed for use in tight spaces within the architecture of new generation Fiber Lasers.

By creating a stable lasing cavity, the T90 FBG product family is an enabling critical component for fiber laser applications in industrial material processing including laser cutting, laser marking, laser welding, and laser drilling, as well as in other fields.

Our state-of-the-art matched FBG pair production system offers flexibility to produce high reflectors and output couplers on a broad range of specialty fibers including single mode (SM) fibers, polarization maintaining (PM) fibers, large diameter fibers, and double-clad fibers. These FBGs exhibit excellent wavelength to temperature linearity.

T90 Matched FBG Pairs are deployed in an increasing range of critical applications and we received excellent customer feedback.


Key Features

Integrated high reflector and output coupler. The precision made FBG pair structure employed in producing the T90 yields a simple laser conditioning configuration of high resolution, linearity, and measurement repeatability.

 Premium technical specifications. High power handling. Excellent wavelength control. High side lobe suppression ratio. Low Insertion Loss. Narrow and broad bandwidth selection. The T90 production station is designed for adapting to custom request specifications and is fully configurable to write FBGs according to requirements within many types of fibers and at tightly controlled physical dimensions. When ordering please include the desired reflectivities, wavelengths, bandwidths and tolerances.
