ClearCut 1939 nm Series Fiber Bragg Grating (FBG)

The ClearCut 1939 nm Series FBG products feature ultra-low insertion loss and low thermal drift performance for the high-power fiber lasers. With the long-term field proven design, these devices can handle up to 200 W at the common 1917 nm, 1925 nm and 1939 nm wavelengths without standing reliability. Customization is available upon request.

793 nm/2 μm High Power (N+1)×1 Pump & Signal Combiner

The 793 nm/2 μm High Power Pump and Signal Combiner exhibits low insertion loss and excellent beam quality for combining up to 6 multimode diode pumps and a signal laser into a double-clad output fiber. The device can handle a maximum 1 kW combined power with stable performance.

Dragon 2 μm 500 W High Power Laser Cable

AFR's Dragon High Power Laser Cable provides the QBH compatible connector for handling up to 500 W output power while enduring high reflection power. Cladding mode stripping, protective window and safety inter lock designs are employed to offer added benefits of stability and safety.

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 Fiber Bragg Grating (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 FBG 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 High Power FBG user experience.

AFR’s ClearCut kW Package-Free Fiber Bragg Grating

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.

Temperature Slope in Air

“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 components, including 1.5 kW ClearCut Fiber Bragg Grating, 6 kW or Higher 7x1 Laser Combiner Module, 6 kW or Higher 18x1 or (18+1)x1 Pump Combiner and Dragon 6 kW Laser Cable.

Advanced Fiber Resources (AFR) released its 1550 nm 20 W Fiber Isolator (PM & SM), which used at the output port of pulsed fiber lasers to prevent any errant beams from returning to the fiber amplifier. This new fiber optic isolator may be used in both common fiber laser applications and ultra-fast lasers with high peak power. Our unique manufacturing process and epoxy-free optical path design enhance the device's ability to handle high power. It is ideal for systems using highly reflective materials, and in high-speed communications.

AFR can also provide a remarkable range of customized optical solutions such as Fiber Delivery Collimator, 100 W Fiber to Free Space Optical Isolator, Integrated Tap Photodiode Isolator (TPDI) so on. For detail, please contact AFR's sales account manager for your requirements.

Advanced Fiber Resources (AFR) released its Integrated Tap Photodiode Isolator integrates the functionality of a miniature polarization insensitive with a tap photodiode for power monitoring in one package. The product provides a more compact solution in EDFA or other modules where both optical Isolator and monitoring function are needed.
