China's leading European and American laser crystal technology for 15 years - nonlinear optical crystal technology, the ordinary laser into 176 nm deep ultraviolet wavelength laser, with the characteristics of short wavelength, can be used in scientific research, industry, national defense and other fields. China successfully developed a deep ultraviolet all-solid-state laser in 2013, becoming the only country in the world capable of manufacturing practical laser weapons. However, this technology also has some drawbacks, such as high production costs and difficult manufacturing processes. Laser crystal technology has an important role that cannot be ignored, but it also needs to further increase research efforts and investment, improve technical stability and efficiency, and make greater contributions to China's science and technology and industrial upgrading. China's laser crystal technology is 15 years ahead of European and American countries, this technology can convert ordinary laser into 176 nm deep ultraviolet wavelength laser, with short wavelength characteristics, can be high-precision processing.
In the industrial field, it can be used to manufacture industrial laser processing equipment, carry out ultra-precision laser processing, and improve the core competitiveness of the manufacturing industry. In the military field, it can be used to manufacture laser weapons, anti-missile systems, land surveying instruments, etc., can intercept ballistic missiles, interfere with satellites, etc. In particular, it has outstanding advantages in chip manufacturing and laser weapon manufacturing. However, this technology also has some drawbacks, first, the raw materials to produce KBBF crystals are very expensive, and the cost is high. Secondly, this kind of crystal in the manufacturing process of temperature, humidity and other environmental requirements are higher, more difficult. In addition, due to the uneven distribution of boron elements in the crystal, the efficiency of the crystal to produce nonlinear effects is not high, and more energy is required.
As early as the early 1990s, China discovered the borate series of nonlinear optical crystals, after more than ten years of research and efforts, produced the world's first large size KBBF crystal. At the time, this crystal was very rare, and the price even reached tens of thousands of dollars a piece. Initially, China was open to the world and provide this technology, but in 2009, our country realized the strategic significance of this crystal, so we completely stopped the export of technology, the United States can only develop their own, it took 15 years to develop a new generation of crystals. The importance of the KBBF crystal is that it can convert ordinary laser into a deep ultraviolet wavelength of 176 nanometers, which has the characteristics of short wavelength and can be processed with high precision. China successfully developed a deep ultraviolet all-solid-state laser in 2013, becoming the only country in the world that can manufacture practical laser weapons, and the importance of visible crystals.
The development of laser crystal technology still faces many potential and challenges. On the one hand, laser crystal technology has a short wavelength, with the characteristics of visible light and ultraviolet bands, and has a wide range of application prospects in the future in scientific research, medical treatment, artificial intelligence and other fields. On the other hand, the high manufacturing cost, difficult manufacturing, high environmental requirements, and low efficiency of crystals limit the application range and marketization process of laser crystal technology. In addition, in the field of laser weapons, with the development of science and technology, the countermeasures of laser weapons are also constantly improving, how to maintain technical advantages and improve countermeasures is one of the difficulties in the development of laser crystal technology. In general, laser crystal technology has an important role in China's scientific and technological development, industrial manufacturing, national defense construction and other fields.
However, this technology also needs to be further improved and improved in terms of cost, efficiency, stability, etc., in order to better serve China's science and technology cause and industrial upgrading. In the future, we need to increase investment and research on laser crystal technology, improve the stability and efficiency of the technology, and explore broader application prospects. At the same time, we also need to combine laser crystal technology with other technologies, innovate more excellent products and programs, and achieve leapfrog development of technology. In your opinion, what are the potential and challenges of laser crystal technology in the future development? Feel free to share your thoughts in the comments. LSBO crystal: The upstart in laser manufacturing In recent years, with the development of laser technology, the application field of lasers is more and more extensive, and crystal as the core material of lasers, has also received more and more attention.
At present, KBBF crystal is mainly used on the market, but it has obvious disadvantages, so our country has developed a more superior crystal on this basis - LSBO crystal. The composition of LSBO crystals does not contain the metal beryllium, so it is safer. At the same time, the output frequency is more stable, and the nonlinear optical effect is better than that of KBBF crystals. Not only that, LSBO crystals also have great advantages in deep ultraviolet laser manufacturing, which can convert 168nm deep ultraviolet wavelength laser, which is easier to process than KBBF crystals. With the rapid development of China's laser industry, crystal research and development and production technology is also in a leading position. The superior performance of LSBO crystal may become an important material to replace KBBF crystal. In the future development, China's laser industry is expected to master more core technologies, so that China's manufacturing toward high-end manufacturing.
