Claims

[Claims for Utility Model Registration] 1. A laser beam that is divided into a main laser beam that performs main processing of the workpiece and a sub-laser beam that performs sub-processing of the workpiece before or after the main processing. , a semi-transmissive mirror disposed in the optical path of the laser beam, a main objective lens that irradiates the workpiece with the main laser beam guided by the semi-transmissive mirror, and a main objective lens with different focusing conditions, A laser processing apparatus comprising: a sub-objective lens that irradiates a workpiece in the vicinity of a condensing position of the main objective lens with sub-laser light guided semi-transmissively. 2. Request for registration of a utility model characterized by comprising a first optical fiber that guides a main laser beam to an objective lens, and a second optical fiber that has a core diameter different from the first optical fiber and that guides a sub-laser beam to a sub-objective lens. The laser processing device according to the range 1 above.
