Abstract
A laser unit comprises a plurality of lasers for emitting laser beams. The laser beams are deflected by deflecting means arranged in the respective optical axes of the laser beams emitted by the respective lasers to be united along a single optical axis. The energy of the laser beams is reduced when deflected by the deflecting means. The reduction level is determined based upon the number of deflecting means and/or types of deflecting means disposed along the respective optical axis of the laser beam. Thus an aggregated energy of the laser beam outputted from the unit can be modulated by turning the individual laser beams ON or OFF.
