    Abstract: A laser uniformly machining apparatus and method thereof are provided. The apparatus includes a laser unit, a shaping element, a collimating element, a scaling element and a focusing element. The laser unit provides a laser beam for machining. The shaping element shapes the laser beam into an annular beam. The collimating element modifies the direction of the annular beam in accordance with the direction of an optical axis to turn the annular beam into a collimated annular beam. The scaling element adjusts the collimated annular beam in accordance with a scaling ratio to produce a scaled annular beam. The focusing element focuses the scaled annular beam. The scaled annular beam is produced by the scaling element to form a focused beam having a uniformly distribution of light intensity in the direction of the optical axis.

    Abstract: A laser machining system and a method thereof are disclosed. The disclosed laser machining system comprises a laser generator, an array photo detector, a processer, and a position controller. The laser generator is configured to emit laser via a first light path onto a work piece. The array photo detector is configured to receive the thermal radiation from the work piece via a second light path, different from the first light path, to generate a thermal radiation image. The processor, electrically coupled to the laser generator and the array photo detector, is configured to calculate a temperature centroid of the thermal radiation image and generate a distance control signal according to the temperature centroid. The position controller, electrically coupled to the processor, is controlled by the distance control signal to make a present distance between the laser machining system equal to a working distance.
