Mar 02, 2021 AFR Releases 2 μm High Power Component Series

AFR 2 μm high-power series addresses the growing demand at the 2 μm region. Its performance and reliability are guaranteed by AFR proprietary design and manufacturing process that suppress unwanted absorption in this wavelength range.

2 μm 50 W In-Line Isolator / 2 μm 100 W Fiber-To-Free-Space Isolator

The polarization insensitive isolator features compact design, low insertion loss, high isolation, high returnloss and excellent environmental stability and reliability. With its record-breaking highest power  handling capability in the market, it is a designer's choice for the 2 μm polarization insensitive fiber amplifers and fiber laser systems. The reflection beam dump port can be reconfigured.

ClearCut™ 1939 nm Series 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 & 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™ 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.

  • Mar 03, 2020 AFR Launches Series of ClearCut™ FBG Products

    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.

  • Apr 26, 2019 AFR Released ClearCut™ kW Package-Free Fiber Bragg Grating

    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 ClearCutkW 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 ClearCutkW 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.
