<p>The method for material working is achieved by means of a laser (L) concentrically guided within a water jet (W). The laser (L) is coupled from behind through a lens into a water jet (W) pushed through a nozzle (D) from an introduction chamber. The laser (L) is then focussed to such as diameter by means of a lens, which is at least half the width of that of the water jet, and the focus plane (F) is arranged at at least double the jet diameter from the nozzle opening plane (E) in the generated water jet (W). The device thus comprises a lens, by means of which the laser (L) may at least be focussed at such a diameter that the focus plane (F) may be possibly coupled into the generated water jet (W) at at least double the jet diameter from the nozzle opening plane (E).</p> |
