Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and device for reducing material vapor which is formed above the operating place of a laser beam, for the purpose of drilling and removing by using laser having a particularly short pulse width (fs/ps/ns). SOLUTION: In this laser drilling and removing method in which the operating place (2a) on a workpiece (2) is loaded by a laser beam (1) generated by laser (la), the operating place (2a) is exposed to an electric field (5).
