Claim Text:
1. A laser machine that operates in one of a standby state of a normal mode, a first energy-saving mode and a second energy-saving mode, in which energy consumption in the first energy-saving mode is lower than energy consumption in the standby state of the normal mode, and energy consumption in the second energy-saving mode is lower than the energy consumption in the first energy-saving mode, the laser machine comprising: a laser oscillator; a cooler that cools the laser oscillator; a controller that controls the laser oscillator and the cooler, to transfer the laser machine among the standby state of the normal mode, the first energy-saving mode and the second energy-saving mode, wherein the controller transfers the laser machine from the standby state of the normal mode to the first energy-saving mode, by stopping a base discharge of the laser oscillator, when a first specified time has elapsed from a stop of laser light emission by the laser oscillator, and wherein the controller transfers from the first energy-saving mode to the second energy-saving mode, by reducing, without eliminating, an amount of laser gas supplied to the laser oscillator, after a second specified time has elapsed from the time when the base discharge of the laser oscillator stops.
