Cladding Power Stripper (CPS)

The multimode optical power stripper (Cladding Power Stripper - CPS) is designed for high power fiber laser and amplifier applications. This device is ideal for stripping residual pump power, ASE and escaped core modes from inner cladding of double cladding fibers while preserving minimal degradation of signal power and beam quality (M2). Reflected signal power into the inner cladding can be stripped out as well.


Key Features

* High Stripping Efficiency

* Low Signal Loss and Beam Quality Degradation

* Wavelength Insensitive

* High Extinction Ratio (for PM version)

* Customized Configurations Available

Note:

§    Bottom side of device must be mounted onto heat sink with good interface contact and active cooling.

§   Stripping efficiency means cladding power attenuation, is defined as -10lg (Po / Pin)Pin is the input power injected into the inner cladding and Po is the output power from the inner cladding.
