Small experiment of super strong laser pointer
After the advent of laser, relying on the mode-locking technology into the femtosecond (10-15 seconds) ultra-high speed era, rapidly applied to physics, biology, chemistry, materials and other frontiers of basic science research. Professor Zewail won the 1999 Nobel Prize in Chemistry for his pioneering work on femtosecond chemistry. Chirped pulse Amplification (CPA) technology pushes lasers further into the super-power era [1], and the scientists involved were awarded the 2018 Nobel Prize in Physics.

What is a super laser pointer?
The first. A super super short laser pointer requires a super strong laser pointer, which is actually a laser pointer with a peak power greater than 1 terawatt (10^12 watts) and a pulse width less than 100 femtoseconds (10^-15 seconds). Its appearance provides unprecedented extreme physical conditions and new experimental methods for human beings. At this point, extreme conditions of high energy densities, even those found in nature only inside stars or at the edges of black holes, have been created in the lab.
The field of ultra-short laser is in the critical stage of making major breakthroughs and developing applications. The world is vigorously developing ultra-strong laser light source, and relying on it to create cutting-edge technology innovation platform. Nearly 40 research and scientific institutions in more than 10 EU countries have jointly proposed the "Extremely Light Infrastructure" (ELI). Their goal is to develop a super short laser with a peak power of 200pw(10^15 watts). In 2017, the user equipment of 10PB ultra-strong and ultra-short laser was built, opening a new era in the research and application of laser-matter interaction. This plan has been included in the roadmap for future development of large scientific equipment in the EU [9-11]. ELI's main research objectives are :100GeV laser acceleration, Vacuum structure of Schweiger field, 1-10KeV coherent X-ray generation and attosecond science and photonic nuclear physics, and the development of 10petaw and even higher ultra-short laser devices.
The high average power super power Laser pointer is an important driving tool in aerospace safety, aerospace environment physics and other applications involving national strategic requirements. The high repetition frequency ultra-power laser is used as the driving tool. Typical. Super lasers with high repetition rates and high average power can produce super proton beams, electron beams, neutron beams, X-rays, gamma rays, and even super terahertz pulses. As a new tool, it can be extended to more cutting-edge major basic scientific research and practical applications such as light nuclear reaction, laser propulsion, nuclear fusion energy and nuclear waste disposal, and disease treatment.
