[pdf — 127k] |Аннотация|

The statistical properties of a radiation spectrum from an electron bunch of arbitrary shape are considered. The kinetic equation for the probability density of the complex vector of total radiation field is derived and solved. The simple way to obtain the moments of the first two orders is presented. Average spectral intensity and its fluctuation are calculated without restrictions to the number of particles in the bunch.

A new approach to the problem of IFE laser driver based on generation and amplification of radiation with controllable coherence proposed and realized at P.N. LebedevPhysical Institute of the RAS had initiated the studies of an interaction efficiency of a partially coherent radiation with matter.Recent results of experiments carried out with the aim to study of the physical processes in targets under illumination by the laser with controllable coherence of radiation are presented and discussed, especially such important laser-matter interaction phenomena as absorption and scattering of laser radiation, the laser radiation harmonic generation,X-ray generation, crater formation and plasma expansion under laser pulse, conversion of laser radiation by means of nonlinear crystals, influence of coherence degree on the processes mentioned above.
