Academy of Sciences-ray machine is a typical representative

The planned capital investment in 2002 alone, that is 047.8 million euros, the investment in subsequent years in proportion to increase. Germany accepted the analysis of type of cell technology research, manufacturing and in the light micro-micro-nano technology, hardware, five-year research project aims the laser light source positioned in the new and ultra fine focusing system, the field reaches 150 ~ 0.1nm spectral super- UV output and energy over the diffraction limit, the differential rate of the high repeatability of less than 100nm near-field lens. laser pointer with remote control can set black screen and hyperlink.Coherent light and micro-nano manufacturing technology, international competition is an important area of current, laser processing technology, the traditional processing technology gave birth to a new Pentium occurred. Predict the future, laser processing technology will be more common applications, with very vast market prospects, and industrial development in the national economy is playing an increasingly important role. China's development in modern light manufacturing, timing and challenges, we must seize the opportunity to greet the arrival times of light manufacturing.
Laser power density, the workpiece temperature increased quickly after absorption of the laser melting or vaporization, even if the high melting point, hardness, large and brittle materials  can also be used laser processing; laser head and the workpiece does not contact, there is no processing tool wear problems; workpiece from stress, pollution is not easy; movement of the workpiece can be sealed in glass or shell of material processing; laser beam divergence angle of less than 1 mm arc, spot diameter can be as small as micrometers, the role of time can be as short nanosecond and picosecond, while high-power laser kW continuous output power and up to the order of ten kilowatts. Laser Technology in China and abroad at the same time started, the technology gap with foreign countries was the smallest high-tech fields. In the country the "Plan" to the "Eleventh Five-Year" with the support of science and technology projects, and gradually formed a Huazhong University of Science and Chinese Academy of Sciences-ray machine is a typical representative of the four research institutions, some of the core technology in laser research and development has become more comprehensive technical achievements, forming a five-level laser technology research center. Among them, the State Key Laboratory of Laser Technology, National Engineering Research Center of Laser Processing, Wuhan National Laboratory for Optoelectronics and the first set of laser Huazhong University of Science subjects are located in Wuhan, became the birthplace of our laser technology.
