Description
The 2.0µm High Power Chirped Fiber Bragg Grating (FBG) from Connet is a specialized component designed for demanding fiber laser applications in the 2.0µm wavelength range. These gratings are written on double-clad specialty optical fibers using advanced chirped fiber Bragg grating technology to deliver high precision, power handling, and thermal stability.
Optimized for both continuous-wave and pulsed high-power fiber lasers, this high power chirped FBG is suitable for configurations requiring single-mode to large-mode-area (LMA) fiber coupling. With pump power handling exceeding 200W and customizable bandwidths and reflectivities, this 2um FBG is available in both recoated and metal heat-dissipating packages, providing flexible integration into a wide range of laser architectures.
Whether you're developing advanced pulsed systems or robust CW fiber lasers, Connet’s chirped FBGs ensure stable cavity feedback, high reliability, and minimal thermal sensitivity across industrial and research-grade applications.
Connet can provide various bandwidths and accurately matched high and low reflectivity gratings for different applications. They are offered in heat dissipative package or recoated only.
