  • Processing device for forming pattern on surface of material by using diffraction of laser beam, and method thereof
    Patent number: 11612961
    Abstract: A processing device to form a pattern on a surface of an object to be processed using diffraction of a laser beam emitted from a laser source, the device including: a main body providing a space to process the object using the laser beam emitted from the laser source; a laser transmission unit formed at a first portion of the main body, and configured to diffract the laser beam so that a diffracted laser beam is emitted toward the object; an actuator formed at a second portion of the main body, and connected to the laser transmission unit so as to change an emission pattern of the diffracted laser beam while rotating the laser transmission unit vertically/horizontally or in a set radius; and a controller provided at a third portion of the main body, and connected to the actuator to control an operation of the actuator.
