Abstract: A gas laser system including a laser oscillator including a device which needs a predetermined standby time until normally starting an operation after stopping an operation due to reduction of a power supplied from a power source unit, a controller, a power reduction detection unit, and a nonvolatile storage unit storing time data of a first time point when the reduction of the supplied power is detected by the power reduction detection unit. The controller calculates an operation stop time of the device, based on time from the first time point to a second point time when a next system activation command is output, and inhibits operation resumption of the device when the operation stop time is within a predetermined standby time.

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 processing apparatus including a laser oscillator, a laser processing machine, and a control part controlling the laser oscillator and the laser processing machine. The control part includes a preparatory operation part controlling the laser processing machine so as to start a preparatory operation for the laser processing if a preparatory operation command is output and, a mode switching part switching an operating mode of the laser oscillator between a standard standby mode before carrying out the laser processing and an energy saving mode with less consumed power than the standard standby mode, and the mode switching part controls the discharge tube voltage so as to switch the operating mode to the energy saving mode before the preparatory operation command is output and to start a switching operation of the operating mode from the energy saving mode to the standard standby mode when the preparatory operation command is output.
