Fiber laser systems have many advantages over other laser systems, including high beam quality, high conversion efficiency, cost-effectiveness, and lightweight. They have been widely applied in areas, such as optical sensing, medical devices, advanced industrial processing, and military defense. With the development of the double cladding fiber technology and laser diode pump technology, the output power of the fiber laser systems has been increased rapidly. However, the unwanted light and optical power increase, due to which the utilization of cladding power stripper becomes essential.
The actual and prime sources of the unwanted light transmitting in the cladding can be divided into 3 sections
Amplified spontaneous emission (ASE)
Residual pump light which is often there at the gain fiber’s end
Core light being reflected into the cladding or leaking into it
All the above-described unwanted light sources are actually spread throughout the chain of components. Excited gain medium naturally generates the amplified spontaneous emission. It is responsible for heavy watts of the entire unwanted light in any high-power laser setting, and actually more in an amplifier.

Now if I talk about its availability in the market. There are several suppliers who can provide you with CPS (cladding power stripper) in all types. In case, you don’t find a standard CPS to fulfill your requirements, manufacturers generally accept the customization of a specially needed CPS or a set of them. You would be able to choose solicitations for specific fiber type, various wavelengths, and the handling power of operations as per your particular requirements.
If you need to buy these power strippers, you may search through the web to find various manufacturers and suppliers. You can simply search for the same, compare their specifications, select the quantity, and place the order as per your need.
