Shanghai-ray machine "photonic technology," International cooperation in the laboratory to open up space for selective laser-induced three-dimensional micro-structure of the new study, based on special selection of doping for the colorless, transparent glass substrate using pulsed laser-induced method, according to the design requirements in Glass succeeded in a three-dimensional laser multi-color patterns. At present, the market's popular glass laser is a laser focus on cracking point of fact, arranged in patterns, which can not be colored. To achieve success in this experiment from full color to the colorless laser laser technology changes have laid a technological basis of the key.

The above-mentioned laboratories to develop technology in the original basic research developed on the basis of. Bairenjihua responsible for the project to the Chinese Academy of Sciences and the National Outstanding Youth Fund project leader Dr. Qiu Jianrong academic leaders for the research group, nearly two years, the selection of laser-induced three-dimensional optical micro-structure of the material that features cutting-edge research, carried out an in-depth system Exploration of research, access to a number of original results, in addition to the outcome of the authority of the international journals, also Nature, Chem. Eng. News magazine made a presentation and so on, and a number of domestic and foreign media (such as Xinhua, China Science and Technology German chemical network, Canada Discovery Channel, Britain and France Materials Today, such as L `Expansion) made a detailed report. This original technology China has applied for patents 4.

The original purpose of the application of innovation. These innovative technologies, the most direct practical application is one of the laser color patterns. The optimum lab in the glass matrix and laser processing and follow-up to optimize the process parameters has done a great deal of study realized the color patterns to choose the color and color control. At present, in a special colorless, transparent doped glass laser in several color patterns. The ultimate aim of researchers is a full color laser laser design and lower costs. To this end, efforts are continuing.

Color laser from the formation of laser micro-zone changes in the structure of materials. When the micro-structure of the line to achieve Optoelectronic degree of integration required by the micro-scale, can be formed with a variety of photo features of the functions of three-dimensional integrated components so as to promote the application of micro-electronics to low-light-level and sub-field . This is the researchers to pursue the application of another goal.

     Usually see most of the crafts is not a true crystal, but a man-made crystal. "Laser" is a man-made crystal (also called "crystal glass") "laser" the most useful tool. Laser laser technology, will be flat or three-dimensional images of the "sculpture" in the internal crystal glass.

This sculpture is an ancient art of carving in general are carved from the outside, the material from the external carving out the desired shape, and the laser can be the same as the Monkey King "in-depth hinterland" to give full play to their hands and feet. View careful, the glass and crystal products for not completely around, "graver" in and out of the opening, on this point, the laser than the Monkey King also smart monkey Sun Lizuan to stomach when they have to have a gap does it! In fact, the principle of laser engraving is simple. To be able to laser engraving glass, it must be greater than the energy density of glass so that the destruction of a critical value, or threshold, and somewhere in the laser energy density and the point at which the size of the spot, with a bouquet of laser spot The smaller the place where the energy generated by the greater density. In this way, through appropriate focus, you can make the laser energy density in the glass and into the processing zone before the arrival of glass below the threshold of damage, and in the hope that the process of the region and over the threshold, the laser in a very short period of time have a pulse , And its energy can make an instant breakdown of the crystal heat, resulting in a very small white spots in the glass-house carved out of pre-shape, glass and crystal, or the rest of the remains as intact.

Laser-assisted laser imaging technology

In fact, the general 3D imaging technology, the use of methods to obtain 3D graphics images, the project highlighted the need to measure the laser target by a laser beam of near and far, the object model and image processing, the whole process is very complicated. To take on many occasions in order to obtain 3D images of objects, expensive and very slow, especially in activities not suitable to capture images of objects. Sometimes the whole process up to tens of minutes, during the filming of the objects can not move. This means that only the use of photography in the landscape and not the object
