    Abstract: The invention relates to an apparatus (100, 200, 300, 700) and a method (400) for machining a workpiece (101) with a laser beam (10a). The apparatus (100, 200, 300, 700) comprises a machining unit (103) configured to provide a pressurized fluid jet (104) onto the workpiece (101) and to couple the laser beam (102) through at least one optical element (105) into the fluid jet (104) towards the workpiece (101). Further, it comprises a sensing unit (107) arranged to receive a laser-induced electromagnetic radiation (106) propagating away from the workpiece (101) through the fluid jet (104) and through at least one optical element, and configured to convert the received radiation (106) into a signal (108). The apparatus (100, 200, 300, 700) also comprises a signal processing unit (109) configured determine a state of machining the workpiece (101) based on the signal (108).

    Abstract: The invention relates to an apparatus (100) for machining a workpiece with a laser beam (101) coupled into a fluid jet. The apparatus (100) comprises a laser unit (101a) for providing the laser beam (101), a nozzle unit (102) with an aperture (102a) for producing the fluid jet, and an optical unit (103) configured to provide the laser beam (101) from the laser unit (101a) onto the nozzle unit (102). Further, the apparatus (100) comprises a control unit (104) configured to control (108, 110) the optical unit (103) and/or nozzle unit (102) to change a point of incidence (109) of the laser beam (101) on the nozzle unit (102). The apparatus (100) also comprises a sensing unit (105) configured to sense laser light (106) reflected from a surface (102b) of the nozzle unit (102) and produce a sensing signal (107) based on the sensed reflected laser light (106). The control unit (104) is particularly configured to evaluate the sensing signal (107) and to determine a defined sensing pattern in the sensing signal (107) indicative of the laser beam (101) being fully and/or partially aligned with the aperture (102a).

    Abstract: The invention relates to an apparatus (100) for machining a workpiece with a high- intensity laser beam (101), the apparatus (100) being configured to provide a pressurized fluid jet (102) and to couple the laser beam (101) into the fluid jet (102). The apparatus (100) comprises a detection unit (103) configured to receive and detect secondary radiation (104) generated by the laser beam (101) in the fluid jet (102). The detection unit (103) includes a sensing unit (105) configured to convert secondary radiation (104) into a detection signal (106). The apparatus (100) is configured to generate, with the detection unit (103), a plurality of detection signals (106) at a single position or at different positions along the fluid jet (102).
