Abstract
(Problem to be solved) To provide a laser beam synthesizing apparatus which is small in size and high in output power. (Means for solving the problem) A convergent angle transforming optical systemis disposed further upstream of the upstream-most position Pa in the positions where the optical axes of beam bundles La, Lb, Lc . . . which are radiated from a plurality of semiconductor lasersA,B,C . . . and converged in the fast axis view by a converging/dispersion lensintersect each other in the fast axis view, and the whole beam bundle made up of the beam bundles La, Lb, Lc . . . passed through the converging/dispersion lensis converged in the fast axis view by the convergent angle transforming optical systemso that the angle of convergence of the whole beam bundle is made smaller in the fast axis view, and introduced into the coreof an optical fiber
