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.
