    Abstract: A laser processing apparatus includes a laser source which generates a laser beam; a scanner unit disposed in an optical path of the laser beam from the laser source and which adjusts the optical path of the laser beam from the laser source in a first direction or in a second direction different from the first direction; and a reflector unit disposed in an optical path of the laser beam adjusted by the scanner unit and which reflects the laser beam adjusted by the scanner unit, where the reflector unit includes a first sub-reflector unit which shifts an optical path of the laser adjusted by the scanner unit in the first direction, and a second sub-reflector unit which shifts an optical path of the laser beam adjusted by the scanner unit in a third direction opposite to the first direction.

    Abstract: A shearing interferometer includes first and second shearing plates disposed opposite to each other. The first shearing plate includes a first front surface and a first back surface, and splits an input beam input to the first front surface into first and second beams reflected at the first front and back surfaces, respectively. The second shearing plate includes a second front surface and a second back surface. The second shearing plate splits the first beam into third and fourth beams reflected at the second front and back surfaces, respectively, and splits the second beam into fifth and sixth beams reflected at the second front and back surfaces, respectively. Each of the first and second shearing plates has a thickness which limits a phase delay between the fourth beam and the fifth beam to a degree determined to allow interference to occur between the fourth beam and the fifth beam.

    Abstract: A window manufacturing method includes providing a mother substrate on a moving stage, the mother substrate including a cutting line; irradiating substantially simultaneously a first beam and a second beam to the mother substrate to cut the mother substrate and to form a target substrate; separating the target substrate from the mother substrate; and providing an etchant to the target substrate to chamfer the target substrate. The first beam is irradiated to the cutting line of the mother substrate, the second beam is irradiated to a point spaced apart from the cutting line of the mother substrate by a distance, and a pulse energy of the first beam is different from a pulse energy of the second beam.

    Abstract: Provided is a laser device including a light source generating a laser beam, a stage, and a lens assembly disposed between the light source and the stage and irradiating the laser beam to a substrate disposed on the stage. The laser device is capable of irradiating a uniform laser beam over an entire processing area to which the laser beam is irradiated. Thus, the laser device may irradiate a uniform laser beam to not only a center area, but also the edge area of the processing area.
