Cladding Power Stripper

The Cladding Power Stripper (CPS) is a critical passive component designed for high-power fiber laser and fiber amplifier systems, where residual cladding light must be safely removed to protect downstream optical components. During pump–signal coupling in double-clad fibers, a portion of the pump light cannot be fully absorbed and may leak into the cladding, especially at pump wavelengths such as 793 nm, 808 nm, 915 nm, 940 nm, and 976 nm. This unwanted cladding power can generate heat, degrade laser performance, or cause severe damage to subsequent optical devices if not properly managed.
