    Abstract: A beam generating apparatus includes a laser light source, a speckle suppressing module, a light homogenizing module and a driving unit. The laser light source outputs a laser beam. The speckle suppressing module includes two biconic lenses and a diffuser. The first biconic lens is disposed on a transmission path of the laser beam. The diffuser is located on the transmission path of the laser beam between the first and second biconic lenses. The light homogenizing module is disposed on the transmission path of the laser beam from the second biconic lens. The driving unit drives the diffuser to move with respect to the laser beam so that the ratio of the M2 of the laser beam exiting from the second biconic lens in a first direction to the M2 thereof in a second direction is greater than 2, wherein the two directions are substantially perpendicular to each other.

    Abstract: A laser cleaning apparatus and a laser cleaning method are furnished, for switching the wavelengths of laser beams furnished by a single laser module using a wavelength switching module and cleaning a test piece using the laser beams having wavelengths and energy suitable for manufacturing needs. The laser cleaning method includes: creating a laser beam; switching the wavelength output by the laser based on process requirements; propagating the laser beam via an optical path propagating module for laser cleaning the test piece; and removing debris. A transfer platform allows movements of the laser beams with respect to the test piece to achieve cleaning of the entire test piece. A control module controls the wavelength switching unit, the laser beam regulating module, and the transfer platform. Total laser cleaning with improved laser cleaning quality is achieved by using these laser beams with the appropriate wavelengths and energy.

    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.
