摘要： A first laser working method includes a step of irradiating the metallic work held by a rotation holding mechanism, with a nanosecond laser beam from a first laser oscillation mechanism, to form a through hole, and a step of irradiating, when the metallic work is rotated under the action of the rotation holding mechanism, the inner wall of the through hole with a picosecond laser beam from a second laser oscillation mechanism, thereby to finish the same. While forming the through hole, metal vapor is sucked from the outside of the metallic work. Then, the gas is fed from the outside of the metallic work, and the inside of the metallic work is suctioned. In a second laser working method, when a lower hole made through is radially enlarged, the exit side of the lower hole is kept lower in pressure than the laser incident (or entrance) side.

摘要： A method of laser machining a small hole with high machining precision in a machined object. The method includes the steps of emitting a laser beam with a fixed optical axis onto a machined object while the machined object is rotated. When the optical axis of the laser beam is fixed in place, the edges of the small hole to be machined are irradiated and the small hole becomes essentially circular even if the cross-sectional shape at the focus of the laser beam is not circular. When the small hole is formed completely through the machined object, a plume is suctioned for removal from a portion of the machined object on a side opposite from the machined hole.

摘要： A sample stage device (10) is so configured as to calculate ideal position information xtg(i), tg(i) per predetermined period that is unaffected by drive conditions relating to gaps (25, 26), etc., and to determine, per predetermined cycle and in real time, deviations dx(i), dy(i) between real-time measured positions x(i), y(i) by position detectors comprising laser interferometers (33, 34), etc., and ideal position information xtg(i), tg(i). In addition, it calculates, based on deviations dx(i), dy(i) thus determined, such speed command values vx(i), vy(i) for motors (27, 28) that measured values x(i), y(i) would follow ideal position information xtg(i), tg(i), and performs stable and high-speed positioning control for a sample table (11) through feedback control that controls speed in real time. Thus, with respect to a sample stage device, it is possible to provide a stable and high-speed positioning control method for a sample table, which is capable of suppressing noise caused by thermal drift and vibration, without being affected by drive conditions, such as the initial states of gaps, etc.
