Description
The GKER Photonics 2.0µm High Power Chirped Fiber Bragg Grating (FBG) is engineered for optimal performance in high-power continuous and pulsed fiber lasers. Utilizing advanced chirped FBG writing technology, these gratings are inscribed in specialty double-clad optical fibers, making them ideal for applications requiring high power handling capabilities of up to 200W. The FBG is suitable for both single-mode and large mode area (LMA) fibers, offering exceptional reliability and stability across a range of demanding environments.
This FBG offers excellent conversion efficiency, a wide variety of fiber compatibility, and an extremely low-temperature slope, ensuring consistent performance even under challenging conditions. GKER provides customizable options, including various bandwidths and reflectivity levels, to meet the specific needs of different laser applications. The product is available in either a heat-dissipative package or a recoated-only configuration, ensuring flexibility in design and application.
