Project summary

The aim of the project is the theoretical and numerical study of the interaction of intense femtosecond and subpicosecond laser pulses with plasmas and dense nanotargets including thin films and clusters.

The main purposes of the investigation are:

  • To study fundamental physical properties of dense nanotargets subjected by intense ultrashort laser pulses, including mechanisms of energy absorption, generation of XUV radiation, highly charged ions production and ions acceleration, generation of superstrong inner electromagnetic fields and excitation of nonlinear plasma motions.
  • To search optimal conditions for production of the effective response of nanotargets in a strong laser field.
  • To control the effect of Coulomb explosion of clusters and foils in a strong laser field.
  • To calculate the average number of photons producing by the dynamic Casimir effect due to strong laser-induced ultrarelativistic deformation of an ideal nonstationary cavity in semiconductor films or plasmas.

Besides, the project proposes a theoretical study of fundamental elementary processes induced by electromagnetic fields of ultrarelativistic intensity in a vacuum and laser plasma. Pair production in a vacuum and in collisions of laser-accelerated particles can be mentioned as examples. Experimental investigation of these phenomena become accessible in nearest decade when the intensity of laser radiation will be enhanced by a few orders in magnitude due to increasing of the power with simultaneous decreasing of pulse duration of infrared and optical lasers. Also fast development of free electron lasers causes a grate hope to enormous increasing of the intensity at short wavelengths in nearest future.

The theoretical work used as a basis of the project has been done in MEPHI and by foreign collaborators.
