Abstract: A laser crystallizing apparatus includes a first light source unit configured to emit a first input light having a linearly polarized laser beam shape. A second light source unit is configured to emit a second input light having a linearly polarized laser beam shape. A polarization optical system is configured to rotate the first input light and/or the second input light at a predetermined rotation angle. An optical system is configured to convert the first input light and the second input light, which pass through the polarization optical system, into an output light. A target substrate is seated on a stage and output light is directed onto the target substrate. A monitoring unit is configured to receive the first input light or the second input light from the polarization optical system and measure a laser beam quality thereof.

Abstract: A method of manufacturing a glass includes forming a first etch protection layer on a first surface of a glass substrate, and forming a second etch protection layer on a second surface of the glass substrate; removing a part of the first protection layer and a part of the second protection layer by applying a laser pulse penetrating the glass substrate from above the first surface of the glass substrate; forming a cut part in the glass substrate by etching the glass substrate using an etching solution; and removing the first etch protection layer and the second etch protection layer. The second surface is opposite to the first surface.

Abstract: The present disclosure relates to an apparatus for forming a line beam. The apparatus includes a laser source, a telescope unit, a beam-transforming unit, a Fourier unit, a long-axis optical unit, and a short-axis optical unit. The laser source is configured to generate input light. The telescope unit is configured to magnify the input light in an X-axis direction perpendicular to an optical axis, which is a progression direction of the input light. The beam-transforming unit is configured to divide light incident from the telescope unit into a plurality of sub-columns. The Fourier unit is configured to uniformly mix the plurality of sub-columns. The long-axis optical unit is configured to uniformly disperse light mixed by the Fourier unit in the X-axis direction. The short-axis optical unit is configured to focus light passing through the long-axis optical unit onto a reference plane, wherein the short-axis optical unit includes a concave reflective surface, and a curvature of the reflective surface is maintained constant in the X-axis direction.
