| China ready to enter the optical era? |
| Throughout the history of human civilization, scientific and technological revolution "is a play a catalytic role in the history of the revolutionary forces ", mainly to promote the development of society through the promotion of production, changes in lifestyle and way of thinking of people . Development of human society from primitive society today can be divided into agricultural and industrial civilizations . According to Marx's historical materialism, philosophical systems , "contradictory relations of production and productivity , to promote the development of human society is the fundamental driving force" , and that the productivity of the three elements are: the production of labor -based tools ; introduced into the production process of labor object ; has some experience in production and labor skills of workers . I think the objective of the core content of labor and labor should be the object of production . From the perspective of the way to look at the technology of production of the industrial revolution , agricultural civilization on a " power processing" mode of production , the impact of human society for thousands of years ; proud industrial civilization worthy of mankind , were also experienced three technology of the industrial revolution , the author objective classification from the perspective of processing methods , respectively considered are: fire , electrical processing and optical processing. Why do you classify it? Taken together the three main signs of Science and Technology Industrial Revolution : the first is a widely used steam engine in the 1760s , the emergence of fire processing tools ; second is the emergence of a wide range of applications of electricity , electrical processing tools in the 1870s ; the third time was a major breakthrough in the 1950s in the field of atomic energy technology, computer technology, space technology, laser technology and biological technology, made light processing occurs production tools . Processing of light manifested in the form of the third industrial revolution , through new laser fusion technology ( atomic technology ) , photonic computer technology ( computer technology ) , laser communication technology, laser measurement technology, laser processing , laser gain material manufacturing technology laser biology techniques, etc. , are driving international economic structure adjustment . Development of science and technology, the interdependence of the world economy more closely , the competition in science and technology have developed to further expand the economic gap with many developing countries . Thus , the third technological revolution for every developing country , in particular China, is both an opportunity and a challenge . Laser since the 20th century , following the atomic energy , computers, semiconductors, another major human invention , known as the " fastest knife" , "the most accurate ruler ," " the brightest light" and " bizarre laser " . Early laser principle has been famous American physicist Albert Einstein discovered in 1916 , but until 1960 was only the first successful laser manufacturing . The laser is in the preparation and production practices theoretical background of the urgent need emerged , it come out , it was a fast developing unusual . People can make effective use of the laser never advanced processing methods , to obtain unprecedented efficiency and results, thus contributing to the rapid development of the productive forces. Laser has played an irreplaceable role in the three human social development : 1 , has been fully penetrated into interdisciplinary , and gave birth to the fiber-optic communications, laser spectroscopy , laser rangefinder , laser radar , laser marking , laser cutting, laser welding, laser weapons , CD , laser pointer , laser vision correction , laser dozens of new disciplines beauty, laser scanning , laser mosquito, laser communications , laser biology , laser medicine , laser micro- fabrication , laser 3D printing. 2, in the economic development of countries plays an irreplaceable role in 2010, the United States assessed the industrial manufacturing , transportation, bio-medicine, information and communication technology applications in areas such as expanding formed by the laser economic contribution , reaching $ 7.5 trillion ; 3 , play an irreplaceable role in the world of national security and defense Modernization . A laser excitation source is constituted by three parts , the work material and the cavity . With over half a century laser technology continues to progress , particularly in terms of improving the work material choice , and structural design resonator excitation source , refrigeration cooling technology, fiber coupling technology , the laser becomes higher electro-optical efficiency , better beam quality , higher output power, transmission more flexibility, greater stability and reliability. Lasers from the beginning of the small power solid-state lasers , high-power CO2 lasers experienced , lamp-pumped lasers, solid-state YAG lasers , Disk lasers, fiber lasers to semiconductor lasers ; output from the optical output of the light guide arm to the fiber. Currently , the industry recognized high-power lasers and fiber lasers Disk is the mainstream market , high power , high brightness semiconductor lasers are the future . Especially those of high optical output power lasers and intelligent robots, automated production lines , process large data processing technology databases and system solutions combining simulation database , will lead the world in advanced manufacturing and industrial intelligence to the world the process of far-reaching impact . For example , laser welding, auto parts and vehicle areas , laser cutting , automated loading and unloading, automatic spray workstations and automated production lines ; laser hybrid welding engineering machinery industry parts , laser blanking, automatic handling and other workstation and production lines ; medical dimensional laser processing equipment industry , laser welding and laser cutting ; laser ranging thick laser welding production line metallurgical industry , steel coil production line welding line , line laser blanking systems , metallurgical rolls and other components remanufacturing equipment, etc. ; various types of equipment, petrochemical industry, laser welding, laser cutting, laser remanufacturing , etc. ; aerospace laser welding , 3D laser cutting, laser gain material manufacturing , etc. ; electronic appliances, photovoltaic, display panels etc. industry -dimensional laser processing line ( laser marking , laser scribing , laser etching , laser drilling , etc. ) Laser processing technology as the core of advanced manufacturing industry processing methods , by virtue of its high efficiency , high quality, pollution, energy saving, high degree of automation is gradually replace the traditional manufacturing methods . Currently , Germany, Japan and the United States to become the leading national laser industry , and produce such as TRUMPF , Rofin-Sinar , Coherent , Spectra Physics , IPG and other famous companies , virtually monopolized the international market. 2013 , China's laser market has exceeded 20 billion yuan of scale , in recent years, the average annual growth rate of approximately 18% to 22 %, has become the world's largest laser processing market. Meanwhile , with the continuous development of China's major infrastructure and major science and technology projects , the laser technology is the penetration and diffusion of a number of areas , the market has great potential. However , most of our laser companies lack innovation and core technology, lasers and components imported mostly take simple extensive integration ; laser processing industrial base level is relatively low, is facing rapid development and continuous innovation situation. By enhancing the core components of the future R & D capabilities , and improve the technical level of the laser processing technology , laser companies in China will provide more opportunities for development. Human society will enter the world of light , and light processing as manifestations of the third industrial revolution is coming, China ready? |
