2.0um High Power Chirped FBG for Fiber Laser
Product Description:
Connet high-quality 2.0um 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 2.0um 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 200W.
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.
Features:
● Extremely Low Temperature Slope● High Conversion Efficiency
● High Power Handling
● Outstanding Reliability
● Wide Variety of Fiber Types
Applications:
● High Power Fiber Laser● Pulsed Fiber Laser
