After focusing through lens, the laser beam form a dot with high energy density in a small area ( the radius is less than 0.003 inch, the effective length is less than 0.2inch), the material in the area will be instantly gasified because of the processing by super energy laser beam. It will form a destructive defect, as moving the laser beam focus continuously; resulting in cutting through the materials.
If the destructive defect is not deep enough, which doesn't cut through the material, then the continuous processing trail can meet the required image. This is laser engraving.
Through controlling the energy density around the focus, if the energy not enough to gasify the material, but it is enough to melt the material. As moving the focus, the melted area will be cooled and solidified as losing the energy. This realized the purpose of fusing together the two materials which is apart originally. This is laser welding.
If reduce the energy density around the focus again, the processing material will be heated but not melted. As moving of the focus, the material crystal structure for the heated area changed, this realized the function of heat treatment. This is laser heat treatment.

About the size of the device, the market has two opposing trends: on the one hand, the devices are getting smaller and smaller, and weld complex; the other hand, the device is greater, and three-dimensional. The continuous development of laser marking machine improved the efficiency.
At present, the medical diagnostic products, continued development towards miniaturization welding technology, which requires several kinds of functional devices can be integrated in the smallest space at the same time. Other welding hair fine flow structure is very difficult, or impossible, and now, even today's low-cost scanning electron microscope laser system can be welding this product. Previously, people will choose the easy-to-focus YAG laser, but the technology costs are very expensive and the technology is not flexible enough. In contrast, the fiber laser or fiber-coupled diode laser cutting technology not only to meet the weld width of 0.1mm, and not subject to the restrictions of the weld shape and size of the chamber.
