ABSTRACT:
A beam-combining laser beam source device comprising first and second laser beam source sections, each of which includes laser beam sources, a collimator optical system and optical path adjusting elements, and a beam-combining optical element. Each collimator optical system is constituted of lens groups corresponding to the laser beam sources, and a common lens positioned so that the laser beams, which have been radiated from the optical path adjusting elements along optical paths parallel and close to one another, impinge upon the common lens. The common lenses are moveable along first directions parallel to their optical axes and along second directions normal to the optical axes. The laser beams which have been radiated from the first laser beam source section and those radiated from the second laser beam source section are moved along directions normal to each other in the optical paths of the laser beams, which have been combined by the movement of the common lenses of the first and second laser beam source sections along the second directions.
