Adopting phase mask technique, the fiber Bragg grating is specially designed for high power CW and pulsed fiber lasers and suitable for single mode fiber to large mode area (LMA) fiber, capable of withstanding power over 3kW.

High power double-clad FBG pair consists of high reflector and low reflector. The low reflector, also known as output coupler, is used to reflect wavelengths of fiber laser. Utilizing chirped phase mask technique, accurately matched high reflector and low reflector can be offered with various bandwidths per users’ specific needs.

Features

• Extremely low temperature rise slope efficiency, suitable for high power operation
• Optimally designed low-reflectivity FBG, reducing reverse light leakage of high-reflectivity FBG
• Excellent reflection/transmission spectrum, increasing stimulated Raman scattering (SRS) threshold
