Abstract
A laser beam combining system, including at least one beam combining unit. The beam combining unit includes reflective device, polarization conversion element and beam combining device. The reflective device includes two reflective surfaces configured to divide a high-polarization laser into a first beam and a second beam. The first beam is incident on the beam combining device. The polarization conversion element is provided on a propagation path of the second beam to convert the second beam into a light having a polarization direction perpendicular to an original polarization direction of the second beam. The converted light is guided to the beam combining device which is configured to combine the first beam and the converted light into one beam for outputting.
