PROBLEM TO BE SOLVED: To provide a laser combining optical device that is able to combine laser beams from a plurality of lasers by means of a simple configuration.SOLUTION: A laser combining optical device 100 according to the present invention comprises: a plurality of semiconductor laser arrays 10a, 10b, and 10c; and reflector elements 11b, 11c that reflect laser luminous fluxes emitted from at least one semiconductor laser array 10b, 10c among the semiconductor laser arrays 10a, 10b, and 10c. When the laser luminous fluxes emitted from the corresponding semiconductor laser arrays 10a, 10b, and 10c are condensed into one condensation point 14, a laser luminous flux emitted from at least one semiconductor laser array 10b, 10c is condensed into the condensation point 14 after reflected by the corresponding reflecting element 11b, 11c. |
