ULTRASTRONG LASER FIELDS PHYSICS

Firstly, the theoretical results of ultrastrong laser fields is reviewed. Secondly, self interaction of pulses of intensities is described as they propagate in dense gases and optical media. Thirdly , generation of ions with a very high degree of ionization is reviewed in a collisionless plasma by ionization in a strong field. The enormous intensity of electric fields in high power ultrashort laser pulses makes it to use laser of this kind in electron acceleration. Fourthly, the generation and application of ultrashort pulses of acoustics and radios is analyzed, the generation of laser radiation harmonic and X ray laser under different conditions is discussed. Further, the high temperature superdense , strong magnet field and enormous pressure plasma close to the parameters of stellar matter is reviewed in the interaction of ultrastrong laser pulses with condensed targets. Finally , deal briefly with the possibly effects of laser excitation of nuclei , nuclear reactions , and electron photon interaction at high energy and also with the proposed experimental investigations.
