Product Description

1.0um High Power Chirped FBG for Fiber Laser

Description

GKER high-quality 1.0um 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 1.0um 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 3000W.

GKER 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.
