Abstract: A laser apparatus includes: a cooling capacity control means which controls the cooling capacity of a heat receiving/cooling unit; a surrounding member which surrounds a dew condensation prevention target unit including a heat generating unit and which reaches a surrounding member equilibrium temperature higher than the maximum dew point temperature within a housing as the temperature of the heat generating unit is increased; and a temperature detection means which detects the temperature of the surrounding member, a control unit compares, while a current output command is being output to a laser power supply unit, a surrounding member temperature with a switching temperature previously set lower than the surrounding member equilibrium temperature and when the surrounding member temperature is lower than the switching temperature, the control unit controls the cooling capacity control means such that the cooling capacity of the heat receiving/cooling unit is a low level whereas when the surrounding member temperature is equal to or more than the switching temperature, the control unit controls the cooling capacity control means such that the cooling capacity of the heat receiving/cooling unit is equal to or higher than a standard level.

Abstract: A laser oscillator comprises a heat exchanger which cools a gas medium. The heat exchanger includes a cooling part which performs heat exchange between the gas medium and a cooling medium, a tubular member fixed to a frame body, and a foreign matter collection container. The tubular member is disposed so that the gas medium which flows out of the cooling part moves along an outer surface of the tubular member and then changes a proceeding direction to flow into an inlet portion. The foreign matter collection container collects foreign matters which are separated from a flow of the gas medium.

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.
