Abstract: A laser device provided with the function of predicting occurrence of condensation and preventing occurrence of condensation in advance. The laser device is provided with a controlling part calculating a reference temperature for judging whether a cooling water feed device may feed cooling water based on a temperature measured by a thermometer and a humidity measured by a hygrometer, and a comparing part comparing a reference temperature and a cooling water temperature. The cooling water feed device is configured to stop the feed of cooling water after a command for starting up the laser oscillator has been output and the cooling water temperature is lower than the reference temperature and to start or continue the feed of cooling water when the cooling water temperature is the reference temperature or more.

Abstract: The laser device of the present invention includes a first temperature sensor which is provided in a housing to detect the temperature of the portion to be cooled, a second temperature sensor and a humidity sensor which are provided outside the housing to respectively detect the temperature and humidity of the air outside the housing. The laser device further includes a judgment unit which judges the possibility of condensation forming on the portion to be cooled by the air outside the housing based on each of the detected results of the first temperature sensor, the second temperature sensor and the humidity sensor, and a notification unit which gives notification of the judgment result of the judgment unit, outside the housing.

Abstract: A gas laser oscillator includes a first control valve for controlling an amount of laser gas supplied into a gas container, a second control valve for controlling an amount of laser gas exhausted from the gas container, and a controller for controlling openings of the first and second control valves. The controller includes a storage unit for storing data indicating a relationship between the laser gas pressure in the gas container, the opening of the second control valve, and the exhaust amount of laser gas, a gas pressure control unit for controlling the openings of the first and second control valves, respectively, such that the laser gas pressure becomes closer to a reference gas pressure, and a gas consumption amount control unit for controlling the openings of the first and second control valves, respectively, such that the exhaust amount of laser gas becomes closer to a target consumption amount.
