Xiao Bian childhood to see other children take a laser toy what, I feel particularly fresh, then even have a laser toy as a life ideal, think about it now is really fun. Flash a dozen years later, more and more laser toys. The use of laser products are also more and more, more and more incredible. China was once a big producer of laser toys. Now it occupies a commanding heights in the laser field and has developed a large number of cutting-edge laser products.
In 2008, China invested 180 million huge sums of money, led by the Chinese Academy of Sciences take the lead in the field of laser as the cutting-edge technology, deep UV solid-state laser cutting edge equipment development projects. By 2011, this project has made technological breakthroughs. Has developed a deep UV laser emission electron microscope, deep UV laser Raman spectroscopy and so on 8 sets of deep-UV solid-state cutting-edge equipment. A series of technological achievements made our country the first and only country in the world capable of mastering practical and sophisticated deep-UV laser technology.
In September 2013, the advanced ultraviolet laser source front-end equipment passed the national acceptance and began to make achievements in such advanced technologies as HTS, graphene, topological insulators, wide bandgap semiconductors and catalysts.
For a long time, our country has been in the field of precision machining major deficiencies, many products look very advanced, but the actual work is very rough, and Germany, Japan, the obvious difference between similar products. Deep UV solid-state laser development and application, is expected to improve China's level of precision machining. Before that, in the field of microelectronics precision machining in the world, China had been importing from abroad and its international discourse power in this field was almost zero.
Take integrated circuits, we use the daily electronic products, almost all inseparable from integrated circuits. For a long time, China imported more annual ICs than imported oil, minerals and grain. Nowadays, in the most advanced 20 nanometer technology field, our country also has a certain right to speak.
Up to now, a basic key technology of deep ultraviolet solid-state laser and a prism coupling technology of nonlinear optical crystal have obtained technical patents respectively in China, the United States and Japan. This ensures that China has the absolute right to speak in the field of deep UV laser output. But this is only the beginning. Chinese scientists and engineers will never have the ultimate goal of exploring advanced technologies because, with them, our country has made remarkable accomplishments one after another.
