A laser-machining device enabling one or more machining targets to be machined at the same time using one objective lens in an industrial micro-machining field is provided. A laser-machining device(400) comprises: a first laser source(12) for emitting a first laser beam(22); a second laser source(14) for emitting a second laser beam(24) spaced from the first laser beam in a predetermined distance; an objective lens part(16) for focusing the first and second laser beams and transmitting the focused laser beams respectively; and a stage which enables a distance from the objective lens part to the stage to be adjusted, and which receives the first and second laser beams transmitting the objective lens part, wherein the first and second laser sources are joined each other such that a distance between an optical axis of the first laser beam and an optical axis of the second laser beam is adjustable. |
