Polarization Beam Combiner

Polarization beam splitter can be used as beam splitters or beam combiners. The output beam which are parallel to input beam is called p-polarized beam while the orthogonal output beam is defined as s-polarized beam. The polarization beam splitter plates are available for red, blue, and green lasers, you can choose the one you require, we will offer our customer the solution for the beam combining.

SLOC can offer complete combining laser system, with the polarization beam splitter, which makes the output power double of the single laser. The system is available for both red lasers, blue lasers and green lasers on your request.
