High-Power Fiber Bragg Gratings
Build better high-power fiber lasers using these output couplers and high reflectors that feature high power handling, precise wavelength control, and low insertion loss.
These FBGs feature high wavelength precision and stability. They also provide a low thermal slope when incorporated in our optional high-power packaging and can handle kW-level power for both pump and signal. Custom designs and prototypes are also available.
High-Power FBGs – Typical Performance
Get these critical laser components with or without high-power thermal packaging: dimensions 60mm (L) x 12mm (W) x 5mm (H). Operating temperature (cooling plate) ≤25 °C.
