Recently, the Shanghai Institute of Optics and Fine Mechanics, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Shanghai Pudong Zhangjiang Hi-Tech Park came good news from the Joint Laboratory of Superconducting Laser Light Sources at Shanghai University of Science and Technology. The pre-research work of SULF made important progress, Successfully achieved 5-watt laser pulse output, reaching the current international leader in similar research. What is "super short laser"? Super short laser light source, is currently the most known light source. The laser light source can output huge energy, power = work / time = w / t, 1 watt (power) = 1 joule / 1 second. From this formula we can see that the same work, the shorter the work time, the greater the power. When time tends to infinity, the power tends to infinity. For a 1 joule of energy, 10 watts of power is achieved if the laser pulse time is reduced from 1 second to 0.1 second. If you shorten 0.001 seconds from 1 second, you get 1000 watts of power. Leng Yuxin, director of the State Key Laboratory of Laser Physics at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, told reporters that 1 watt tile equals 1000 trillion watts, which is equivalent to 500 times the average power of the global grid. The 5-watt laser pulse output successfully achieved by Shanghai Institute of Opto-Electronics was a femtosecond (one-thousandth trillionth of a second) level on a time scale, with a power of 5,000 trillion watts. With this light source, it is possible to produce controlled and extreme conditions in the laboratory and to conduct a series of physical phenomena. "Super short laser" what's the use? Super short laser is the latest development of international laser technology frontier and competition focus areas, with great scientific and technological significance and application value. It can be used to develop desktop electron accelerators and ultra-fast X-ray sources to image and detect atomic motion in proteins and reveal the mysteries of life. It can be used to develop laser proton knives for the treatment of cancer. It can also be used to generate antimatter and to study astrophysics and The origin of the universe may also be used for the detection of vacuum structures and dark matter in the future. This reporter has learned that in recent years, many countries in the world have invested heavily in developing 10-watt watts (1 watts = 1 trillion watts, equivalent to 500 times the global power grid average power) of large super-short ultra-short laser device Development, competition is extremely fierce. The EU-supported Extreme Light Infrastructure (ELI) project plans to build 10-pw laser user devices by 2018. France and Britain are also developing their own 10-pw laser devices. The United States, Russia, Japan, Research and design of strong ultrashort laser device. The Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences (CASU) - a joint effort of Shanghai UCT Superlattice Laser Light Source Laboratory made important progress in the pre-research on the ultra-short ultra-short laser experiment device (SULF) and successfully achieved 5-watt laser pulse output. The SULF project is planned to 2017 is the first in the world to achieve 10-watt laser output target. The development of Shanghai super-short ultra-short laser experiment device (SULF) was incorporated into the first batch of major projects of building a world-class science and technology infrastructure cluster in Shanghai with a global innovation hub. It will also be a comprehensive national science center of Shanghai Zhangjiang One of the core platforms. Super short laser experiment device will not only meet its own research needs, but also as a research and development platform, open to users. The first batch of experimental devices will be completed three user experimental terminals, serving the extreme conditions of materials science, ultrafast chemistry and macromolecular dynamics and ultrafast subatomic physics, universities and research institutes and enterprises at home and abroad for full liberalization, and fully integrated into Shanghai Light source device, the formation of multi-disciplinary comprehensive research platform.
