1.5um High Power Chirped FBG
Description
The 1.5µm High Power Chirped Fiber Bragg Grating (FBG) by Connet is a premium optical component designed to meet the demands of high-performance laser systems operating at 1550nm. Written in specialty double-clad optical fibers, this chirped fiber Bragg grating leverages advanced fabrication techniques to ensure high precision, low thermal drift, and excellent reflectivity. Ideal for both continuous wave (CW) and pulsed high-power fiber lasers, this 1.5um FBG is tailored to applications where stability, mode control, and thermal handling are critical.
The product is optimized for use with single-mode and large mode area (LMA) fibers, featuring handling capacity of up to 50W pump power. Offered exclusively in recoated form, the grating is available in multiple bandwidths and reflectivity configurations to meet specific laser cavity requirements. Its outstanding optical performance and reliability make it an essential element in today’s industrial, medical, and scientific fiber laser systems.
Connet can provide various bandwidths and accurately matched high and low reflectivity gratings for different applications.
