1.5um High Power Chirped FBG for Fiber Laser
Connet high-quality 1.5um fiber grating reflectors (also called Fiber Laser cavity mirrors) are written in specialty double clad optical fiber with optimized chirped Fiber Bragg Grating (FBG) writing technology. They are specially designed for 1.5um high power continuous and pulsed fiber lasers, suitable for single-mode fiber to the large mode field (LMA) fiber, the pump power handling capacity can reach more than 50W.
Connet can provide various bandwidths and accurately matched high and low reflectivity gratings for different applications.
