Abstract
A laser machining device can be used to direct two independent laser beams onto the same machining field in a single machining process. This can be achieved by using an at least partially reflective optical element, configured such that the first laser beam is essentially transmitted and the second laser beam is essentially reflected. The beam paths of the two laser beams are varied independently of each other by two deflection units before they strike the at least partially reflective optical element. This results in a large number of advantageous possibilities for the precise and continuous machining of materials.

A device for machining objects using laser beams, comprising:
- a first deflection unit, adapted to direct a first laser beam via a first projection lens onto a partially reflective element;
- and
- a second deflection unit, adapted to direct a second laser beam via a second projection lens onto the partially reflective element, wherein the partially reflective optical element is configured such that it essentially transmits the first laser beam and essentially reflects the second laser beam and wherein the partially reflective optical element is arranged in such a way in relation to an object to be machined, that the two laser beams are directed onto the object after at least one of transmission and reflection.
A device for machining objects using laser beams, comprising:
- first deflection means for directing a first laser beam via a first projection lens onto a partially reflective element;
- and
- second deflection means for directing a second laser beam via a second projection lens onto the partially reflective element, wherein the partially reflective optical element is configured such that it essentially transmits the first laser beam and essentially reflects the second laser beam and wherein the partially reflective optical element is arranged in such a way in relation to an object to be machined, that the two laser beams are directed onto the object after at least one of transmission and reflection.
