We supply a high-power Fiber Bragg Gratings (FBGs) product line specially designed for high-power fiber laser applications, meeting strict requirements for performance and durability.

Key Advantages of High-Power FBGs – Coherent

• High Power Handling: Capable of handling several kilowatts for both signal and pump, ideal for high-power fiber laser systems.
• Precise Wavelength Control: Ensures exceptional wavelength accuracy with a central wavelength deviation (DCWL) ≤ 0.2 nm, maintaining stable performance.
• Low Insertion Loss: Optimized design minimizes insertion loss, enhancing overall system efficiency.
• Excellent Thermal Stability: When combined with optional high-power thermal packaging, FBGs maintain stable performance under varying temperature conditions.
• Customizable Design: Coherent offers tailor-made FBGs in terms of size, wavelength, configuration, and mounting to suit specific applications.
