Summary:The object of the present invention is to provide a compact and high output laser light coupler device. The solutions includes that each laser light beam La, Lb, Lc is emitted by a plurality of semiconductor laser 11A, 11B, 11C, passes a convergence lens 120, and is converged in the FAST axis. And light axis of each light beam La, Lb, Lc installs a convergence angle varying optical system 30 which is more upstream than the most upstream position Pa which is crossed position, looked in the FAST axis. The convergence angle varying optical system 30 makes convergence angle of the whole light beam which is made of each light beam La, Lb, Lc and which passes through a convergence-divergence optical system 120, become smaller convergence angle in the FAST axis, and makes the whole light beam emit into the core 41 of optical fiber 40.
