    摘要： A laser machining apparatus machines a workpiece at uniform intensity by converting a CO2 laser beam to uniform intensity using an intensity-converting element and a phase-matching element. The optical transmission system is configured such that the starting point of the laser beam pointing vector and the exit face of the intensity-converting element are mutually conjugated with respect to the optical transmission system. This structure offers stable machining by ensuring that the laser beam always enters the intensity-converting element at its center, even if the pointing vector of the laser beam shifts.

    摘要： A harmonic Q switch laser device and its control method for obtaining a stable laser pulse while protecting a nonlinear optical crystal used for a wavelength conversion are presented. In this laser device, in a pause period of a laser train, a Q switch which is turned on makes the laser oscillates spuriously and continuously, and prevents a gain from accumulating in a gain medium Before a generation of a laser pulse, the Q switch is turned off for a specified period to raise the laser gain, so that a pulse of a specified magnitude is generated from the first shot when turning on the Q switch.

    摘要： A laser processes a circuit board including at least two layers. The two layers are a conductive layer with a plurality of holes and an insulating layer. The conductive layer is disposed on a surface layer of the insulating layer which is to be processed by applying a laser beam to portions of the insulating layer corresponding to the holes of the conductive layer. The circuit board is irradiated with the laser beam, and a reflected laser beam is detected, whereby the laser processing of the insulating layer corresponding to an abnormal hole in the conductive layer is stopped, if the detected value of the reflected laser beam is an abnormal value differing from a desired value. Also, the insulating layer corresponding to the hole is processed when the detected value of the reflected light conforms to the desired value.

    摘要： A laser machining apparatus includes a laser generator for generating a laser beam and a driver unit for moving the laser beam relatively with respect to a workpiece as to emit the laser beam on the workpiece. The laser beam includes plural laser pulses. The laser pulses have spots each having a longitudinal direction. The driver unit moves the laser beam in the longitudinal direction relatively with respect to the workpiece so that the spots overlap each other. This laser machining apparatus can process the workpiece at high quality and high productivity.

    摘要： A reliable galvano-mirror employed for laser machining is disclosed. The mirror is far reduced its weight for getting a higher rotation. On the rear surface of the mirror, a lightweight rib-structure, which is formed from a mirror support beam centered across the surface and some ribs extending from the beam, holds the mirror. Against a distortion occurred in rotating at high speed, the mirror is provided with a high rigidity. And the mirror is structured integrally with the motor shaft holder. Besides, a slit is formed between the rib disposed close to the holder and the support beam centered across the rear surface of the mirror. Providing slit enables to minimize a local distortion caused by a stress from fastening screws to attach the mirror to the motor shaft.
