摘要： PROBLEM TO BE SOLVED: To obtain a laser oscillator that can accurately and simply adjust a total reflection mirror and a partial reflection mirror inside the oscillator.
SOLUTION: In the laser oscillator: a laser medium gas is excited between discharge electrodes for generating a laser beam; the laser medium gas whose temperature is increased by discharge is led to a heat exchanger via a duct for cooling; and two pairs of laser oscillation sections, where the cooled medium gas is circulated between the discharge electrodes again, are arranged facing each other inside a case so that the flow of the laser medium gas is in an opposite direction. The laser oscillator has a window provided at the side of the case and a first mirror that is provided in the duct to observe an aperture for guiding the laser beam from the window, and confirms whether the light of visible light laser for adjusting the mirrors inside the oscillator exists at the center of the aperture or not.

摘要： PURPOSE:To obtain a laser oscillator where laser ray is stabilized in quality and a laser machining device which is protected against deterioration in machining precision and set free from machining failures. CONSTITUTION:A laser oscillator is equipped with a resonator composed of a total reflection mirror 8 and a mirror holder 15 which fixes the mirror 8, a control plate 14 equipped with a cooling water path 14a through which cooling water is fed to cool down the total reflection mirror 8 or the mirror holder 15, and an elbow 17A which is fixed to the inlet/outlet of the cooling water path 14a and set freely rotatable in optional directions. By this setup, even after the elbow 17A is completely fixed to the control plate 14, it can be rotatable in a required direction, and furthermore a mirror-polished surface 18 of the control plate 14 and the total reflection mirror 8 are prevented from being distorted owing to the rotation of the elbow 17A.

摘要： PROBLEM TO BE SOLVED: To make feasible of effective venting from a piping within a short time. SOLUTION: Bypaths 18, 18 are provided between a cold water path and a cooling down path 13. Besides, the bypaths 18, 18 are provided with bypath valves 17, 17. Furthermore, the cold water path 12 and the cooling down water path 13 are respectively provided with the cold water path transfer valves 16, 16 and the cooling down water path transfer valves 19, 19. Next, when these cold water path transfer valves 16, 16 are closed and the bypath valves 17, 17 and the cooling down water path transfer valves 19, 19 are opened to start both of the circulating water pumps 6 and 9, the circulating water amount can be increased by the operation of the two pumps 6 and 9, thereby enabling the venting work from the cooling down path 13 to be performed within a short time.

摘要： PURPOSE:To provide a device capable of surely making check, maintenance, display and control at the time of a failure of optical parts such as condenser lens of a processing head an resonator mirrors of a laser oscillator. CONSTITUTION:An electric conductivity is detected at all times through an electric conductivity detector 15 from a conductive material 14 stuck to the condenser lens 4 held in an insulating holder 25 and the PR mirror 11 and TR mirror 12 of the resonator of the laser oscillator 1 and, therefore, the electric conductivity degrades and the fault of the condenser lens 4 is detected in case of the deterioration and failure of the condenser lens 4. Since the electric conductivity detector 15 and a controller 6 are wired, the irradiation with lens light 2 is stopped when the detected signal is processed by the controller 6 and then, the fault is detected from the condenser lens 4. As a result, the failure of the optical parts, such as condenser lens 4 of the processing head and resonator mirrors of the laser oscillator, is monitored at all times and there is an effect of safely executing the processing.
