Abstract
A laser cutting machine capable of producing focal points with the same size comprises a working platform, a pen housing, and a beam expander. The pen housing is movably provided on the working platform for receiving laser beams from a laser tube to cut an article provided on the working platform. The beam expander is provided in a laser beam output path between the laser tube and the pen housing, so that the laser beams are output after passing sequentially through the beam expander and the pen housing, wherein the beam expander is provided movably on the working platform, and the displacement of the beam expander is changed with the displacement of the pen housing, so as to produce focal points with the same size after the laser beams are output.
