Over the next decade, the laser intensity may be increased to 1026-1028W/cm2, this high-intensity laser particle can be accelerated to 1012-1015eV, and will be the study of particle physics? Gravitational physics? Nonlinear field theory? Super high-pressure physics? astrophysics and cosmic ray research is a powerful tool [1].
High-power ultrashort pulse laser technology, in the laboratory created unprecedented conditions of extreme states of matter, such as high electric field? Tour guides can point out and explain the sight spots by using the high power green laser pointer .Strong magnetic field? High energy density? High pressure and high light energy of the electronic jitter? High electron acceleration, which kind of extreme physical conditions, only in the nuclear explosion center? stellar interior? star hole edges can exist in the interaction between it and the material, resulting in a highly nonlinear and relativistic effects, resulting in a new field of physics, for more cross-disciplinary field of frontier research has brought historic opportunities and expand the space.
This kind of high power 100mW laser pointer has been popular with tour guides.Current international has been established in some laboratories a few tens of TW to PW laser system, in the mid-1980s, before the laser intensity is about long-term stay in 1014W/cm2, which is due to nonlinear absorption effect with with increasing laser intensity increased rapidly after the mid-1980s, the use of chirped pulse amplification (chirped pulse amplification, CPA), the laser intensity increased 6-7 orders of magnitude, in the CPA technology, or a femtosecond Dispersion of picosecond pulses by grating it in the time scale broadening of 3-4 orders of magnitude, thus avoiding amplifier saturation and very high intensity in the nonlinear optical effect produced by damage to the amplifier parts, after After amplification, then another grating compression of the pulse width of femtosecond or picosecond width of the back to get 1019W/cm2 to 1022W/cm2 power density on the target. The high power Blue Laser Pointer has also been applying in military exercises.CPA TW ultrashort pulses of laser optics applied research in France The? Lund University, Sweden? Mark-Plank Institute in Germany? University of Jena in Germany? Japan JAERI and China Academy of Engineering Physics? CAS Shanghai Institute of Optics and Fine Mechanics? Institute of Physics? The high power 5mW laser pointer has also been using in military commanding.China Institute of Atomic Energy are all built in Japan Atomic Energy Research Institute and CPA using a combination of deformable mirror technology, the use of low f values of the parabolic mirror, the laser focus on 1μm spots, can further improve the power density on the focal spot, but because of the amplifying medium on the saturation energy per unit area flux and optical components damage threshold limits the maximum per unit area of light intensity I th = hν3σΔν ac2, this value is about 1023W/cm2. the United States is planning to build 10LLNL 18W (exawatt) and 1021W (zettawatt) of the laser device, in order to obtain 1026W/cm2 -1028W/cm2 power density on the target.The high power 200mW Laser Pointer has been also using for measuring buildings in distant range.
