Abstract
The present invention discloses a laser beam combination apparatus, comprising: a water cooling plate, a beam combiner and two laser arrays; each of the laser arrays comprises N lasers, wherein N is a positive integer more than 1; the two laser arrays are fixed on an upper surface and a lower surface of the water cooling plate, respectively; and the beam combiner performs a spatial beam combination, a polarization beam combination or a wavelength beam combination of laser beams output from the two laser arrays. Thus it can be seen that in the technical solution provided by the present invention, arrays of lasers are arranged on the upper and lower surfaces of the water cooling plate, and under the condition that a beam combination is performed on the same number of laser light beams, the water cooling plate is used in a high efficiency to decrease the volume and weight of the laser light beam combination apparatus, save the material of the water cooling plate of the laser light beam combination apparatus, and reduce the cost of the laser light beam combination apparatus, thus meeting the production and processing requirement of the laser light beam combination apparatus, and promoting the continuous development and progress of the laser light beam combination technique.
