Abstract: A laser processing head is provided with: an optical component for splitting a laser light into a laser light and a laser light; a scanning unit for scanning the laser light; a light reception unit for detecting the intensity of the laser light; a second shutter that shifts between a closed position in which the laser light is blocked and an open position in which the laser light is transmitted; and a focal distance adjustment unit for adjusting the focal distance of the laser light. The second shutter is arranged between the optical component and the focal distance adjustment unit.

Abstract: A laser processing device includes: a controller unit, a light source unit, and a head unit. The light source unit includes a laser light source, a light-source drive circuit, and a light-source control unit. The light-source control unit is configured so as to transmit a response signal in response to a request signal. The controller unit includes a light-source power circuit that supplies a light-source drive voltage to the light-source drive circuit. A main control unit of the controller unit: transmits the request signal; determines, on the basis of the received response signal, whether the light source unit can be driven; supplies the light-source drive voltage to the light-source drive circuit from the light-source power circuit in the case in which it is determined that the light source unit can be driven.

Abstract: A laser processing device comprises: a first shutter that shifts between a closed-state position for blocking a laser beam and an open-state position for allowing the laser beam to pass; a second shutter that shifts between a closed-state position for blocking laser beams and an open-state position for allowing the laser beams to pass; a first closed-state sensor that detects that the first shutter is disposed at the closed-state position; a first open-state sensor that detects that the first shutter is disposed at the open-state position; a second closed-state sensor that detects that the second shutter is disposed at the closed-state position; and a second open-state sensor that detects that the second shutter is disposed at the open-state position.
