摘要： In a gas laser blower, the lower end opening of the oil passage (14) extends below the liquid level of the oil reservoir (17), so that the internal chamber (18) of housing and the oil passage (14) are separated by the oil within the oil reservoir. Further, a cylindrical guard (24) is disposed around the lower bearing (6) which supports the shaft so that the oil and oil mist scattered from the bearing are caught by the guard (24) and is returned to the oil reservoir.

摘要： In a blower for compulsorily circulating a laser gas for a gas laser apparatus, a shaft (2) of an impeller (1) is fitted with an intermediate member (66) that rotates together therewith, and rings (641, 642) are fitted individually in annular grooves (651, 652) formed on the intermediate member (66). On the other hand, a bearing holder (60) for holding a bearing (5) that supports the shaft (2) is provided with a ring holder (63) having an inner wall kept normally in contact with the respective outer peripheral surfaces of the rings (641, 642). As a result, narrow axial gaps between the rings (641, 642) and the annular grooves (651, 652) prevent gaseous impurities from getting into a gas laser circulation path through a bearing (5).

摘要： A laser beam machine for carrying out a machining operation by converging a laser beam emitted from a laser resonator and irradiating the converged laser beam onto a workpiece. A beam interceptor (21) is arranged across a light path extending from a total reflection mirror (2) of the laser resonator (1) to a surface of the workpiece (5) and has a small inertia, and the position thereof is controlled at a high speed to permit the passage of the laser beam and to intercept the laser beam. The beam interceptor (21) is controlled in such a manner that the laser beam is allowed to pass during a full-scale discharge and is intercepted during a seed discharge. Accordingly, even if a seed discharge exists while a high-reflectivity material, for example, is machined, a laser oscillation of a composite resonator including the workpiece (5) can be reliably prevented.

摘要： A laser resonator allows internal optical mirrors to be cleaned easily and minimizes any contamination of the internal optical mirrors. The laser resonator has normally closed cleaning windows disposed immediately in front of output, rear, and folding mirrors for inserting a cleaning instrument therethrough for cleaning these mirrors. A gas inlet discharge tube holder has a discharge tube coupling which interconnects the spaces in parallel discharge tubes for transmitting a laser beam therethrough. The gas inlet discharge tube holder also has a gas flow bypass for bypassing a laser gas that circulates through the discharge tubes. The internal optical mirrors can be cleaned easily with a cleaning instrument inserted through the cleaning windows. As the internal optical mirrors do not need to be removed for cleaning, they and an external optical system are not required to be readjusted for alignment of their optical axes. Any contamination of the internal optical mirrors is minimized because no laser gas flow is caused in the discharge tube coupling.

摘要： There is provided a turbo blower for lasers which is capable of effectively cooling a shaft and bearings thereof. Oil held in a shaft support member is drawn up via an oil inlet port by a centrifugal force generated by rotation of the shaft, and passes through a cooling oil passage extending through the shaft to be discharged from an oil outlet port provided below an upper one of rolling bearings as the bearings. The oil discharged from the outlet port returns via an oil return passage to an oil sump. While passing through the oil return passage, the oil is cooled by a coolant circulating through an coolant passage. Further, part of the oil discharged from the oil outlet port is supplied to the upper one of the bearings for lubrication. On the other hand, part of the oil held within the shaft support member is drawn up along a tapered portion of an oil suction head by the centrifugal force generated by rotation of the oil suction head for lubrication of a corresponding one of the rolling bearings. A large amount of oil flowing through the cooling oil passage can deprive the shaft and the rotor of heat, thereby effectively cooling the bearings as well.

摘要： A solid-state laser oscillating device which is inexpensive and capable of obtaining a high power. A plurality of laser crystals (YAG laser crystals, etc.) (1a, 1b, 1c) are arranged along the optical axis of an optical resonator so as to maintain optical contact with one another. Adjacent ones of the laser crystals have surfaces facing each other with an adhesive layer (10, 20) interposed therebetween, to form an array in a straight-line as a whole. An adhesive having a low light absorbance with respect to a laser beam of oscillation wavelength or an excitation light is used for forming the adhesive layers (10, 20). If the refractive index of the adhesive is substantially equal to that of the laser crystals, optical matching is achieved. The adhesive layers (10, 20) may be replaced by some other transparent material. The adjacent laser crystals may be arranged with a narrow gap therebetween or held in surface contact with each other.

摘要： A laser oscillator device applies a high-frequency voltage to a plurality of discharge regions through a dielectric for producing a high-frequency discharge for laser pumping. Various interferences in the laser oscillator device are prevented to allow the device to produce a stable output. The laser oscillator device includes DC power supplies (DC12a, DC13a, DC13c, DC13d) and high-frequency power supplies (RF12b, RF13b, RF14b, RF15b) which are integrally coupled to prevent electromagnetic interference through cables for allowing stable laser oscillation and also to prevent various other interferences.
