Project summary

The Project objective is design and creation of the high-power solid-state lasers on the base of the pulse compression for the purposes of the super-intense light field generation and Investigation of this field interaction with the matter.

The tasks of the Project:

In the course of the Project fulfillment there would be carried out the mastering of the new architecture of the high-power solid-state lasers for various applications, providing some advantages (the cost, in particular) in comparison with the common lasers.

The super-intense light fields, provided by the elaborated lasers, will give the possibility to carry out the investigations in the principally new branches of physics: nonlinear atomic physics, the physics of the super-dense plasma, generation of intense X-ray pulses, relativistic nuclear optics and laser quantum electrodynamics.

Elaborated during the Project fulfillment technologies of the fabrication of the new optical materials (glasses, crystals, coatings), new optical components (diffraction gratings, amplifiers, compressors etc.) as well as methods of intense pulse generation, methods and software for numerical calculations, may be used in the various related fields of science and engineering.

Supposed results:

1. Elaboration of the new optical methods and schemes of the intense laser pulse generation, improving significantly the parameters of the solid-state lasers.

2. Creation of the efficient solid-state lasers with the high radiation power (up to 100 TW) and intensity up to 1020 W/cm2.

3. Elaboration of the theory, analytical models and numerical software for the analysis of the interaction between sub-picosecond intense laser pulse and condensed or gaseous target.

4. Creation of the X-ray source with the intensity up to 1015 W/cm2; possible applications - medicine, biology, technology, optics, quantum electronics and plasma physics.

5. Creation of the new means of the picosecond plasma diagnostics.
