Abstract
Abstract FIRST AND SECOND LASERS HAVING DIFFERENT CHARACTERISTICS ARE FOCUSED ON THE SAME SPOT SO THAT THE DIFFERENT CHARACTERISTICS CAN BE EMPLOYED ON THE SAME SPOT. FOR EXAMPLE, A SOLID-STATE LASER CAN MELT A SPOT ON A WORKPIECE, AND A FLUID-STATE LASER CAN MAINTAIN THE LIQUID SPOT. A POSITIONING AND FEEDING TABLE IS PREFERABLY EMPLOYED TO LOCATE THE SPOT ON THE WORKPIECE AT WHICH THE COMBINATION OF THE LASERS IS ACTIVE.
