LASER PROCESSING APPARATUS

摘要

A laser beam collecting optical system is provided with a laser beam source for projecting laser beams; a beam collecting optical system arranged between the laser beam source and a medium, for collecting the laser beams in the medium; and a laser emitting point moving means, which can move a position of a laser emitting point of the laser beams along the optical axis of the laser beams, corresponding to a refraction factor of the medium wherein the laser beams are to be collected and a distance between the surface of the medium and a position whereupon the laser beams are to be collected. ® KIPO & WIPO 2007
