Project summary

Research of substance behavior in ultrahigh fields is one of the priorities of the fundamental science. For this purpose the lasers of femtosecond range are under development now. We propose the alternative approach.

The goal of this work is to demonstrate experimentally the possibility to create powerful sources of radiation focused in a wavelength order size and to obtain the quasistationary field (t і 10-9 s) with (109 – 1010) V/cm intensity to investigate atoms behavior in such fields.

To solve this problem it is suggested to use the laser pumped by radiation of shock wave with the following parameters: energy of 102 – 104 J and pulse duration of 10-9 s. Radiation will be focused by the lens with the relative aperture 1:1. We suppose to compensate laser beam and lens aberration using phase conjugation method. With such conditions the radiation intensity at the focal spot is something like 1019 – 1021 W/cm2.

In contrast to the similar fields, created by femtosecond laser radiation, in a proposed method we can implement quasistationar interaction of monochromatic field with atoms.

The work will be accomplished by the demonstration experiment. Basing on obtained experimental and theoretical data, designs and demonstration experiments we suppose to prepare the program of studies and our proposals to create a test bed to study substance behavior in ultrahigh electromagnetic fields.

Scientific significance of the project is to obtain new results on self-phase conjugation of light beams in real time and to create new means of ultrahigh electromagnetic field obtaining to study substance behavior in extreme conditions.

The project will give an opportunity to scientists and engineers, related to weapons, to redirect their talents to solution of fundamental scientific tasks of peaceful application.
