PURPOSE: To provide a device which converges and focuses plural laser beams from laser light sources in spatially different positions to form one common optical point with almost all output quantity of convergent light. CONSTITUTION: The device which converges and focuses plural laser beams from laser light sources, which are arranged in spatially different positions, to form one common optical point consists of plural laser light sources 1, 2, and 3, which have such characteristics that they can generate convergent or divergent light having a common focus Fc of all light sources by themselves or combination with optical means 4, 5, and 6, and a common optical means 7 which receives convergent or divergent light from laser light sources to converge and focus it on one common optical focus F.
