The utility model discloses a laser cutting device, equipment includes cutting head, laser instrument, mixed light device and reflective phase retardation device, mixed light device and reflective phase retardation device set gradually in the light path of the emergent light of laser instrument, the mixed light device is arranged in sneaking into the visible light laser beam of laser emitting, the mixed light device will include the mixed light bundle outgoing of visible light and laser and arrive among the reflective phase retardation device, reflective phase retardation device changes the laser beam of linear polarization into the laser beam of circular polarization, the laser beam of circular polarization is through the cutting head outgoing to by on the work piece that cuts. The utility model discloses a reflective phase retardation device changes the linear polarization laser beam of circular polarization into, not only makes cutting joints wide unanimous, has reduced a string sediment phenomenon, moreov
