Advanced Fiber Resources (AFR) is pleased to announce the release of three new FBG based products: ClearCut™ FBG Reflector for picosecond fiber lasers, Pulse Stretcher for femtosecond fiber lasers, and 1939 nm Series Fiber Bragg Grating for infrared lasers.

“These new products were developed under our unique ClearCut™ FBG technology that has demonstrated excellent performance on low temperature gradient vs. power and long term reliability. We have delivered kW level FBG products in volumes for the past two years and they are well received in the market. These new products extend the great performance to some of the specialty and rising applications.” said Kevin Zhang, AFR’s VP of Engineering.

The Fiber Bragg Grating Reflector features with no extra dispersion, package-free design and flexible mechanical performance, ideal for picosecond fiber laser system. It can be written on wide range of fibers, such as PM 980, PM 1060, PM 10 / 125, and used at around 1030 nm and 1064 nm center wavelength.

The Pulse Stretcher creates large amount of dispersion to stretch short pulse to sub nanosecond level, ideal for femtosecond laser system. It can be supplied with either package-free or packaged designs. Available for various amounts of dispersion and fiber types.

The 1939 nm Series Fiber Bragg Grating features with low temperature slope, pump power handling of up to 200 W and packaged inside our long-time proven high power package. Center wavelengths available for 1917, 1925 or 1939 nm, as special infrared laser source needed in the market.

All three products have passed reliability qualification test. As always, we can customize wavelength, power handling, fiber type, package type and any other parameters. Contact us to discuss your special needs.

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 FBG user experience.

AFR’s ClearCut™ kW Package-Free Fiber Bragg Grating

Controlling temperature has long been a challenge when using FBG 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.

Advanced Fiber Resources (AFR) released several new high power products, including 1500 W ClearCut™ Grating, 6 kW or Higher 7x1 Laser Combiner Module, 6 kW or Higher 18x1 or (18+1)x1 Pump Combiner and Dragon™ 6000 W Laser Cable.
