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 turbo blower for a laser device, including a shaft having an impeller on one end thereof, a pair of bearings, having inside grease spaces and supporting the shaft Non-contact seal portions are provided for preventing an outflow of grease, whereby other spaces for retaining the grease are formed on either side of the bearings. Although the grease in the inside spaces of the bearings is urged to escape from the bearings by the centrifugal force of the rotation of the shaft, the grease is prevented from flowing out of the spaces on either side of the bearing by the non-contact seal portions.

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： A laser machining apparatus capable of performing a high-speed and high-precision machining of a workpiece. One end of each of a first-axis and a second-axis expandable arms is supported on a fulcrum. The fulcrum is angularly movably within a predetermined range about the fulcrum in a plane parallel to a machining plane. A machining head is supported at a joint point of the first-axis and second axis expandable arms. Each arm has a ball screw and a cover having an expandable and contractible tube structure, and the machining head has a ball nut threaded to engage with the ball screw. As the ball screw is rotated by a servomotor, the arm extends and contracts to move the machining head. A Z-axis adjusting mechanism is provided between a joint portion of each arm and the machining head and a machining nozzle that is disposed on a tip of the machining head. A three-dimensional parallel drive system or a combination of a serial drive system and a parallel drive system may be used to drive the machining head.

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 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. The laser oscillator device includes a DC power supply (16), and a high-frequency power supply (18, 19, 20, 21) for converting a DC voltage into a high-frequency voltage. The DC power supply (16) and the high-frequency power supply (18, 19, 20, 21) are coupled to each other by a filter (30). The filter (30) prevents a high-frequency component from being fed back from the high-frequency power supply (18, 19, 20, 21) to prevent the laser oscillator device from operating unstably due to parasitic oscillation. Other arrangements are disclosed for preventing interference between the high-frequency power supply and the DC power supply.
