Cladding Power Stripper (CPS)
Description
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.
Feathure
High Stripping Efficiency
Low Signal Loss and Beam Quality Degradation
Wavelength Insensitive
High Extinction Ratio (for PM version)
