According to the latest report of the National Academy of Sciences, National Academy of Engineering and National Medical College (NASEM), the United States is at a disadvantage in the second revolution of ultra-fast ultrafast lasers; It has a wide range of applications in medicine and national security.
At present, 80% to 90% of the world’s super laser systems are deployed outside the United States, and all the highest-power scientific lasers currently under construction or already built are located outside the United States. . The report made five recommendations that would enhance the United States’ position in this area.
This report focuses on the super-pulse laser. This laser source accelerates the collision of the fundamental particle beam, drives the nuclear reaction, heats the material to the conditions of the star, and even creates matter from the vacuum. These powerful lasers originated in the United States. However, research funding agencies in Europe and Asia have invested heavily in new partnerships and facilities over the past decade to use these super-strong lasers in a wide range of scientific fields.
The committee that conducted the study and report believes that ultra-fast ultrafast lasers have broad applicability in the scientific field and can be used in nuclear weapons reserve management, industry, and medicine. The committee also said that super-strong lasers have formed a very important scientific system, and already have a large technical cluster, but it is scattered among different disciplines, and the cooperation between industry and government is limited. There is currently no single federal agency that is the manager of ultra-strong laser research. There is no cross-institutional management in the United States. Projects under different missions, without overall coordination, sponsored by several different federal agencies are also located in Europe. . To strengthen integration and coordination in this area, the committee recommends that research institutions invite scientists to identify important performance parameters of laser facilities to best meet research needs; highlight parameters that exceed current state of the art in cutting-edge science, such as peak power. , repetition frequency, pulse duration, wavelength, and adjustable focus intensity.
The committee also requested the US Department of Energy (DOE) to lead a comprehensive cross-institutional national strategy for ultra-strong lasers, including plans to develop and operate large-scale laboratory projects; university-sponsored medium-scale experiments Room projects; and technology development plans for technology transfer between universities, the US industry, and national laboratories.
The synergy between ultra-strong lasers and existing infrastructure (such as particle accelerators) is considered a key to US laboratories in comparison to Europe’s Extreme Light Infrastructure (ELI) program. Advantage. Based on this, the Commission recommended that the US Department of Energy develop a plan to build at least one large-scale open super-strong laser facility using the other major scientific infrastructure of the US Department of Energy’s complex. In addition, cooperation between universities, laboratories, and industry is necessary to maintain and update the talent pool, and cooperation between these departments has proven its role.
The report points out that the current situation can be improved to develop a strong national talent pool and a strong technical foundation for this fast-growing region. The committee’s final recommendation is to require agencies to develop programs for US scientists and engineers, including medium-sized infrastructure, the operation of the US Super Laser Science Program, the development of key infrastructure technologies, and participation in international institutions such as the ELI program.
