Abstract:
For present time by petawatt laser systems achieved the intensities of 1022-103 W/cm2, and the agenda is the task of creating the laser systems with exawatt peak power (1 EW = 1018 W) in order to obtain ultra-relativistic intensity ~ 1025 W/cm2. The intensities of that level open new ultrarelativistic phase in the development of laser physics in the formation of which would be essential the effects of quantum electrodynamics. In this paper we develop the basic principles of creation of multi-beam femtosecond laser systems with peak power of exawatt level, based on coherent field combining of beams with phase-frequency controlled radiation of beams by optical frequency standard (optical clock).
