With the advantages of cold working, short pulse and ultra short pulse laser pointer have entered the field of precision machining such as micro-nano processing, fine laser medical, precision drilling and precision cutting. Because the ultrashort pulse can inject the processing energy into the small action area very quickly, the instantaneous high energy density deposition changes the electron absorption and movement mode, avoiding the effects of laser linear absorption, energy transfer and diffusion, and fundamentally changes. The interaction mechanism between laser and matter has become a powerful research tool in the fields of nonlinear optics, laser spectroscopy, biomedicine, strong field optics, and condensed matter physics.
Compared to femtosecond lasers, picosecond lasers do not need to be broadened and compressed for amplification, so the picosecond laser pointer is relatively simple, cost-effective, and reliable, and is capable of high-precision, stress-free on the market today. Micro processing. However, ultra-fast and super-strong is the two major trends in laser development. Femtosecond lasers also have greater advantages in medical and scientific research. In the future, it is very likely that a next-generation ultra-fast laser will be developed that is faster than a femtosecond laser.
The ultra-fast laser pointer has a long history in industrial applications and is a hot spot for laser applications in developed countries such as Europe and the United States. At present, the ultra-fast laser market is basically dominated by foreign companies, accounting for nearly 90% of the global market share. However, the Chinese government, scientific research institutions and enterprises attach great importance to ultra-fast lasers, and the policy is tilted and enterprises are increasing their investment in difficult technologies. Advanced level. Tsinghua University, the Institute of Physics of the Chinese Academy of Sciences, Opto-mechanical Institute, Huazhong University of Science and Technology and other universities are vigorously promoting ultra-fast laser research; domestic laser companies represented by Dazu, Huari, Anyang, and Bellin are also pushing ultra-fast lasers. Industrialization of technology. It is reported that Huari Laser is expected to achieve mass production of femtosecond lasers during the year, which will break the monopoly of high-power ultra-fast lasers in Europe and the United States, and drive the ultra-fast laser equipment industry application market of more than 10 billion yuan. The localization of picosecond and femtosecond ultrafast lasers will reduce the cost of using domestic applications by at least 30%-40%, and the market will be ready in the future.
With the launch of Germany's "Industry 4.0" and "Made in China 2025", the demand for high-end manufacturing, intelligent manufacturing, and high-precision manufacturing will increase significantly, especially in the rapid development of consumer electronics, which will bring transparent and translucent materials to laser. Pointer processing huge market demand is a new blue ocean market. Ultra-fast lasers and advanced micro-nano processing technologies will usher in new development opportunities. It is estimated that by 2020, the ultra-fast laser market will exceed US$1.5 billion.
