Abstract: A method of manufacturing a substrate includes: irradiating, along a first path, a laser beam emitted from a source onto a substrate, wherein the substrate includes a target layer of the laser beam, and wherein the substrate is disposed on a stage; and irradiating, along a second path, a portion the laser beam, which was emitted from the source and reached the target layer, by reflecting the laser beam back onto the target layer using a reflection mirror. An area of a second region of the target layer is greater than an area of a first region of the target layer, wherein the laser beam is irradiated along the second path in the second region, and the laser beam is irradiated along the first path in the first region.

Abstract: A laser optical system including: a beam splitter configured to split a laser beam into a first light and a second light by reflecting a portion of the laser beam and transmitting another portion of the laser beam; a first reflective member located in a path of the first light and reflecting the first light; and a second reflective member located in a path of the first light and reflecting the first light toward the beam splitter after the first light is reflected by the first reflective member, wherein a portion of the first light reflected toward the beam splitter is incident on and passes through the beam splitter and at least partially overlaps the second light.
