Advanced Fiber Resources (AFR) drew a lot of attention at the 2019 Laser World of Photonics with the unveiling of its ClearCut kW Package-Free Fiber Bragg Grating, a new device that improves High Power FBG user experience.

Controlling temperature has long been a challenge when using Fiber Bragg Grating devices. The typical solution has been to dissipate excess heat using a mounting structure or package. The extra mounting, however, creates difficulties with installation and true temperature monitoring of the FBG area.

AFR’s ClearCut kW Package-Free FBG may be bent and mounted in any position along with other fibers, eliminating the need for a separate mounting structure or package and maintaining an ultra-low temperature rising without adding extra cooling. Additionally, this product may add an FBG area temperature monitor, to help users or engineers improve real-time data analysis, and ensuring system safety.

“The ClearCut kW Package-Free FBG product well represents AFR’s technical capability. It makes AFR a more One-Stop-Shop for fiber laser components. We are committed to the continuous advancement in product technology and product quality.” said Kevin Zhang, AFR’s VP of Engineering.

Small in size, big on capability, AFR’s ClearCut kW Package-Free FBG ensures more than 2.0 kW pump power and 1.5 kW signal power handling with outstanding reliability. It has passed the critical qualification tests including low/high temperature storage, temperature cycling, fiber pull and high humidity.
