Abstract: Provided are a variable pulse width flat-top laser device and an operation method therefor. A variable pulse width flat-top laser device includes a light source unit including first and second laser light sources driven at different times to respectively emit pulse-type first and second laser beams, a beam shaping unit configured to shape the first and second laser beams emitted from the light source unit into flat-top laser beams, a combination/split unit located between the light source unit and the beam shaping unit, and including a first beam combination/split unit configured to combine optical paths of the first and second laser beams and split a combined optical path into at least two optical paths so that the split at least two optical paths are directed to different regions of an incident surface of the beam shaping unit, and an imaging optical system configured to time-sequentially overlay the flat-top laser beams shaped by the beam shaping unit on a target object to form an image.

Abstract: Provided is a laser device. A laser device includes a light source unit configured to emit a first laser beam and a second laser beam, and a beam shaping unit configured to receive the first laser beam and the second laser beam on an incident surface and to shape the first laser beam and the second laser beam into a first processing beam, wherein the beam shaping unit is further configured, to have the incident surface including four quadrants, to receive the first laser beam on a first quadrant and the second laser beam on a second quadrant, and to shape the first laser beam and the second laser beam being emitted at different timing from the first laser beam into the first processing beam.
