Patent ID: 7902483

Claim:
A laser machining apparatus comprising: a workpiece fixture for fastening a workpiece, a first laser removing device having a first laser source, a first laser beam and a first laser beam outlet for laser drilling a workpiece using first operating parameters, and a second laser removing device having a second laser source, a second laser beam and a second laser beam outlet for machining a workpiece using second operating parameters that are different from said first operating parameters, wherein: the second laser removing device is configured to remove material of the workpiece in layers, the first and second laser beam outlets of the first and second laser removing devices are fixedly mounted offset from each other with respect to at least one axis, the first laser removing device comprises one or more of the following operating parameters: a pulsed laser light having a laser pulse frequency of 0.1 to 100 Hz; a laser pulse duration of 0.1 to 20 ms; a pulse peak performance >1 kW; a laser performance of 300 W to 3 kW; an energy per pulse of 1-100 J; and a laser type comprising one of a diode-pumped solid-state laser or a lamp-pumped solid-state laser; the second laser removing device comprises one or more of the following operating parameters: a pulsed laser light having a laser pulse frequency of 1 to 100 kHz; a laser pulse duration of 10 to 1500 ns; a laser performance of 10 to 200 W; an energy per pulse of 1-50 mJ; and a laser type comprising a quality-switched solid-state laser; and the workpiece fixture is configured to move the workpiece between operating windows of the first and the second laser removal devices.
