Abstract

A method and a device for detecting a focal position of a laser beam, particularly a machining laser beam in a laser machining head, includes an optical element which is arranged in the laser beam converging toward the focal point and which is designed to outcouple a reflection from the laser beam path, and a sensor arrangement which is designed to detect beam characteristics of said laser beam in the region of the focal point in the laser extension direction, and which measures the outcoupled reflection of the laser beam at at least two locations that are offset to one another in the extension direction, in order to determine the current focal position.
