摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for removing a soldered electronic component that can quickly remove a soldered section that is judged to be failure in an electronic component without thermally affecting a peripheral electronic component, a printed circuit board, and the like. SOLUTION: A heated gas is jetted from a gas nozzle 30 to an electronic component 41 that is soldered on a plurality of wiring electrodes of a printed circuit board 42, and at the same time a laser beam L where an optical axis is arranged in the gas nozzle 30 is irradiated planarly, thus melting the entire soldered section of the electronic component 41 nearly simultaneously, and hence removing the electronic component from the printed circuit board 42.

摘要： PROBLEM TO BE SOLVED: To provide a scrape cutting method and apparatus which can cut continuous scrapes growing while machining into short scrapes by low power laser beam. SOLUTION: A laser oscillator 13 is connected to a scrape cutting head 12 which can move integrally with a runner for a cutting device 23 of a machine tool 11. The swarf cutting head 12 includes a light-gathering means composed with a collimator-lens 34 and an objective lens 35, and a light-route changing means composed with a polygon-mirror 36 for example. Laser beams 41 emitted from a laser oscillator 13 converts to parallel beams by the collimator-lens 34, reflects to reflecting surface 43 of the polygon-mirror 36, and, passing through the objective lens, concentrates and irradiates to the continuous scrape 32 growing from a work 25. Laser beams 42 reflected from the reflecting surface 43, scanned by the rotation of the polygon-mirror 36 to follow continuous scrape' s movement, irradiates longer the same spot of the scrape, so that laser beams, even if small power, has an ability to cut the scrape.

摘要： PROBLEM TO BE SOLVED: To reduce the variance in height of a bump and to shorten the processing time in a texture processing where pulse laser light obtained from continuously oscillated laser light is used to form the bump on a glass substrate. SOLUTION: At the time of irradiating a glass substrate 8 with a converged light spot, the irradiation section of the converged light spot is preliminarily formed in an ellipse, and its minor diameter ds is set in the peripheral direction of the glass substrate 8. The converged light spot is scanned relatively in the direction of the minor diameter from the irradiation start point shown by a solid line to the irradiation end point shown by the double dotted chain line through the irradiation halfway point shown by the alternate short and long dash line. As the result, the irradiated area is approximately circular to form a false circle-shaped conic bump. The pulse width and the ellipticity are optimized without increasing the power density of laser, thereby realizing a prescribed bump height and forming a bump plane into a circle regardless of the increase of the relative rotation speed of the substrate 8.

摘要： PURPOSE:To transmit laser beam in the optical fiber placed opposite each other in time sharing to a machining point so as to enable multi-point machining by rotating and slide moving on the optical axis the optical system inserted between the integrated laser oscillator consisting of a bend mirror/beam collective lens and optical fiber. CONSTITUTION:After the laser beam 7 emitted from a laser oscillator 1 is collected through a bend mirror 2 and collective lens 3, the converged beam spot is made incident on the end face of an optical fiber 4. When the integrated optical system consisting of a bend mirror 2 and collective lens 3 is rotated around the optical axis O, the converged beam point scans so as to move peripherally around the rotating center, switching in sequence by time sharing method and being made incidence on each optical fiber 4 dispersedly arranged on the scanning locus. In the case of the arrangement that many optical fibers is placed in short pitch interval, the laser beam is smoothly subjected to time sharing, being made incidence on the optical fiber 4 to be transmitted.

摘要： PURPOSE:To maintain a reflectivity high for a long period by composing a reflector for surrounding a laser medium and an exciting light source to be contained in a sealed vessel of an elliptical cylinder of glass finished in a mirror surface, and using a gap formed to the inner wall in the vessel as a cooling medium passage. CONSTITUTION:A reflector 10 is formed of heat resistant glass, formed as a thin elliptical cylinder for surrounding a laser medium 1 and an exciting light source 2, and its outer peripheral surface is formed as a mirror surface 11. The reflector 10 is carried at a holder 20, the holder 20 is formed of a metal block having excellent thermal conductivity, the inner surface 21 opposed to the reflector 10 is formed substantially in an elliptical state along the outer periphery of the reflector 10 of the mirror surface 11, and a gap G is provided between the inner surface 21 and the surface 11. The gap is used as a cooling medium passage to cool the elliptically cylindrical reflector from both side surfaces with cooling medium to prevent peeling of mirror surface forming metal coating from the glass and damage of the glass based on thermal stress. Thus, its reflectivity can be maintained highly for a long period.

摘要： PURPOSE:To avoid a decrease in the reflection factor of a coating due to a cooling medium, particularly pure water, by finishing a reflection surface of an excitation light reflector for a solid laser device into a silver mirror surface and by coating the silver mirror surface with a thin film of titanium oxide so as to use the surface as a reflector. CONSTITUTION:A reflector 10 comprises a cylindrical silver mirror surface 12 in an body 11 and by coating the silver mirror surface 12 with a titanium oxide thin film 13. The mirror surface is formed in, for example, an elliptical surface. A laser medium 1 and an excitation light source 2 are rod-shaped and they are disposed so that their centers are positioned on two respective focuses of the ellipse of the mirror surface. Almost all excitation light EL from excitation light source 2 are reflected by the elliptical surface of the silver mirror surface and toward the laser medium 1. When the laser medium 1 is not a cylindrical rod but a flat slab, the silver mirror is shaped different from the ellipse, and two excitation light sources 2 are generally disposed according to a pair of flat planes. An inner cavity surrounded by the silver mirror surface 12 of the reflector 10 is filled with a cooled medium CM, e.g., pure water. The water is made to flow in the direction perpendicular to the surface of the drawing to cool the laser medium 1 and the excitation light source 2 intensely.
