LASER PROCESSING DEVICE AND LASER PROCESSING SYSTEM

摘要

A laser light source unit (24) is provided with a laser oscillator (26), and a beam expander (27) integrally fitted in a state of being positionally adjusted with respect to the laser oscillator (26). The beam expander (27) is secured to an end surface of the laser oscillator (26) where the light emission port is positioned. An opening (33a) is provided to a casing (33) which houses a galvano scanner (36) in a location corresponding to the beam expander (27). The laser light source unit (24) and a scanner unit (25) are joined to each other via a packing (50) in a state in which the beam expander (27) is inserted into the casing (33) via the opening (33a). In other words, the laser light source unit (24) is configured so as to be attachable to and detachable from the scanner unit (25) in a state in which the beam expander (27) can be inserted into the casing.
