The In-line Polarizer is designed to pass one specific linear polarization light while blocking the other polarizations. WSP’s in-line polarizer can effectively convert non-polarized light into polarized light with high polarization extinction ratio (PER) with extremely low insertion loss. If used inside a laser oscillator it guarantees a high PER linear polarization output by effectively suppress the unwanted polarization states and eliminate instabilities by polarization state hopping.
If used outside the laser cavity it can enhance the extinction ratio of signals with its excellent PER. It is ideal to be used for fiber lasers oscillators and amplifiers, high speed communication systems and test instrumentations where high PER signals are required.
