Laser is the 20th century one of the greatest inventions, with the thermonuclear technology, semiconductor technology, electronic and computer technology and aerospace comparable to a world of the major scientific and technological achievements.


Laser with high directional, high monochrome and high coherence of the characteristics of the industrial, agricultural, biological, commercial, widely used in areas such as national defense. In the 1990s, a new application of laser technology - laser marking technology, using laser beam irradiation surface, the surface instantaneous melt even gasification, which formed on the surface in the text, pictorial and other permanent marker. As laser irradiation to the workpiece surface is partial, high temperature processing site to the non-irradiated sites have little effect, the heat affected zone of the workpiece small workpiece without basic deformation without loss.


In this paper, laser marking system for a comprehensive discussion, with an emphasis on laser marking systems, optical system research and control methods, and understanding of storage based on the lattice algorithm design.

The radium shoots is one of 20th century greatest inventions, the significant technical achievement which is which with the thermonuclear technology, the semiconductor technology, the electronic computer and the aerospace
technology compares favorably with attracts worldwide attention.


The radium shoots has high domain application and so on the directing
property, high monochromatic and high coherence characteristic, in
industry, agriculture, biology, trade, national defense is widespread.
In the 90's, item of brand-new radium shoots the application
technology — radium to shoot hits the sign technology, shoots the
light beam illumination work piece surface using the radium,
instantaneous causes the work piece surface to melt the melt even to
gasify, thus forms permanent mark and so on the writing, design in the
surface. Because the radium shoots shines to the work piece surface is
partial, processing spot temperature extremely high, to non-
illumination spot influence really micro, therefore the work piece
heat-affected zone is very small, the work piece basically does not
have the distortion, does not have loses.
