Abstract: A laser control device includes: an averaging circuit that applies a primary delay filter to an actual instantaneous value; a data processing unit that applies a primary delay filter to an actual average value H, thereby calculating an actual average value S; a reference value generation unit that generates an reference value; and an output reduction determination unit that determines output reduction. In a case in which pulse on time in the output command value exceeds a sum of the processing period and start-up time of a power supply, if the actual instantaneous value falls below the reference value, it is determined that an output is reduced; and in a case in which the pulse on time is equal to or less than the sum, if the actual average value S falls below the reference value, it is determined that an output is reduced.

Abstract: A laser control device includes a processor configured to control, when a control circuit of a laser device detects occurrence of an abnormality in a laser oscillator or a laser optical system and stops laser output from the laser oscillator, the control circuit based on a result of determining whether to enable or disable re-outputting of laser light from the laser oscillator by inputting, to a classifier, input data being at least a part of environmental data and state data about the laser device in a predetermined period including a stop time of laser output. Then, the state data and the input data in the predetermined period include at least one of time-series data about a light amount of laser light and time-series data about a light amount of return light propagating in a direction opposite to a direction of the laser light in the predetermined period.

Abstract: A laser apparatus calculates a temperature of a temperature increase portion that is raised in temperature by reflection light, and determines and outputs an emergency optical output command with the aim of ensuring that the calculated temperature does not exceed a first predetermined temperature, which is set at a lower temperature than an upper limit heat resistance temperature, and if necessary, controlling the temperature to or below a second predetermined temperature set at a lower temperature than the first predetermined temperature. When the emergency optical output command is to be output, a control unit switches an optical output command output thereby to the emergency optical output command and outputs the emergency optical output command.

Abstract: A laser machining apparatus capable of extending the life time of a guide laser is provided. A laser machining apparatus 1 includes a cutting head 2 that irradiates a machining laser light to a machining target W, a guide laser 5 that irradiates a visible guide light to the machining target W, and a power supply 6 that supplies electric power to the guide laser 5. The laser machining apparatus 1 further includes a controller 7 that performs control so that, before the machining laser light is irradiated from the cutting head 2 to the machining target W and laser cutting starts, electric power is supplied from the power supply 6 to the guide laser 5, and the guide light is irradiated from the guide laser 5 to the machining target W according to an output position of the machining laser light output from the cutting head 2 so that the output position of the machining laser light is ascertained. The controller 7 has a laser output setting unit 4 capable of adjusting an output of the guide light of the guide laser 5 within a range where the visibility of the guide light is secured when the guide light is output from the guide laser 5.
