Abstract
A beam-combining laser beam source device comprising laser beam sources; collimator optical systems positioned in optical paths of laser beams radiated from the laser beam sources. Each of the collimator optical systems is constituted of a first lens section and a second lens section. Optical path adjusting elements are positioned in the optical paths of the laser beams in order to radiate the laser beams along optical paths parallel and close to one another. A support member supports the laser beam sources, the collimator optical systems, and the optical path adjusting elements. Each laser beam source and the corresponding first lens section are combined into a laser beam source unit and mounted on the support member, the positions of the laser beam source and the first lens section having been adjusted with respect to each other. The second lens section corresponding to the laser beam source unit is mounted on the support member with the position of the second lens section being adjusted with respect to the position of the laser beam source unit in a plane which is normal to the otpical axis of the laser beam source unit.
