The report is devoted to the management of pulse duration and temporal intensity contrast ratio enhancement of laser pulses with petawatt power. The theoretical and experimental results of second harmonic generation process under strong influence of cubic nonlinearity will be discussed. The outcomes of implementation of small-scale self-focusing suppression method at intense laser beams (1.4TW/cm2) will be considered.
