Wideband depolarizers for Raman pump lasers are designed for PDG reduction in Raman amplifiers. They provide <5% DOP and operate to specification at any wavelength in the 1400-nm range. They can be used either with a single high-power pump and provide randomized polarization, or following a polarization multiplexer to randomize both polarization states. An integrated polarizer is available.
