The laser-cutting head has a laser-beam inlet, a cutting nozzle (30) and an articulated laser-beam passage between the inlet and the cutting nozzle (30). The laser-beam passage has a first rotatable segment (10) connected to the inlet, a second segment (20) connected to the first rotatable segment (10) for receiving the laser beam, and four mirrors arranged in the first and the second segment (10, 20) for transmitting the laser beam from the inlet to the nozzle (30). The cutting nozzle (30) is connected to the second segment (20). <IMAGE>
