Classification: CPC B  H | IPC B  H

Claim 4:
5. 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 a dew point inside the laser oscillator meets a condition one and a condition two,
wherein the condition one is when the dew point inside the laser oscillator is lower than a first dew point at which a monolayer or less of water molecules is adsorbed, and
wherein the condition two is when the dew point inside the laser oscillator is equal to or higher than a second dew point at which more than a monolayer of water molecules is adsorbed inside the laser oscillator and lower than a third dew point at which dew condensation starts to occur inside the laser oscillator,

wherein the first dew point is a value corresponding to an upper limit value of water vapor pressure in a state in which a monolayer or less of water molecules is adsorbed inside the laser oscillator,
wherein the second dew point is a value corresponding to or higher than a lower limit value of water vapor pressure in a state in which more than a monolayer of water molecules is adsorbed inside the laser oscillator, and
wherein the third dew point is a value corresponding to an upper limit value of water vapor pressure in a state in which more than a monolayer of water molecules is adsorbed inside the laser oscillator and being higher than the second dew point.
