Claim 12:
13. A dehumidification management method for a laser device including a laser oscillator, a dehumidifier for dehumidifying the inside of the laser oscillator, and a controller,
wherein the controller is configured to control the dehumidifier such that such that a water vapor pressure inside the laser oscillator meets a condition one and a condition two,
wherein the condition one is when water vapor pressure inside the laser oscillator is lower than a first water vapor pressure at which a monolayer or less of water molecules is adsorbed, and
wherein the condition two is when water vapor pressure inside the laser oscillator is equal to or higher than a second water vapor pressure at which more than a monolayer of water molecules is adsorbed inside the laser oscillator and lower than a third water vapor pressure at which dew condensation starts to occur inside the laser oscillator.
