Claim 12:
13. A method for aligning the laser beam for machining the workpiece by using the apparatus according to claim 1, the method comprising
providing the laser beam,
providing the laser beam to a nozzle unit with an aperture for providing a water jet,
changing a point of incidence of the laser beam on the nozzle unit so as to perform an automatic scan of at least a part of a surface of the nozzle with the laser beam,
sensing laser light reflected from the surface of the nozzle unit to produce a sensing signal based on the sensed reflected laser light,
evaluating the sensing signal during the scan to detect an appearance of a defined sensing pattern in the sensing signal evaluated during the automatic scan,
determine the laser beam being fully or partially aligned with the aperture of the nozzle based on the appearance of the defined sensing pattern.
