<p>In a wave combining device, for improving the combining efficiency, a pair of dichroic mirrors (16a, 16b) is employed and three or four laser beams (11a to 14a) which are osciallating in a same direction, are introduced into said mirrors such that for P waves one of the dichroic mirrors (16a) and for S-waves the other dichroic mirror (16b) are used selectively in accordance with the oscillation directions of said laser beams to be combined. The two beams leading the dichroic mirrors (16a, 16b) are PS combined by a polarizing beam splitter prism (15) into a single beam to be coupled, for example, to an optical fiber (18). <IMAGE></p> |
