2 kW Bidirectional Fiber Cladding Power Stripper
The cladding power stripper (CPS) can remove cladding light to ensure the high beam quality and stability of the high power fiber laser system. It is one of the important core devices for the stable operation of a high power fiber laser system. This paper uses a new bidirectional low-high-low CPS based on the segmented corrosion method. The local maximum temperature of CPS is 31.2 ℃, the temperature increase rate is as low as 3.5 ℃/kW, and the stripping efficiency is 20.1 dB when the input power is 2051 W without active cooling. The bidirectional design of CPS can gradually strip the backlight in the fiber cladding, and further, improve the safety and reliability of the fiber laser system. This research can provide important device support for high power fiber laser systems.
