Abstract A possibility of using self-phase modulation and cascaded quadratic nonlinearity effects for the enhancement of the temporal intensity profile is analysed theoretically in application to petawatt pulses at a kJ energy level. Preliminary experiments at a petawatt CETAL laser facility demonstrate the reduction of a pulse duration from 46 fs down to 29 fs by using the self-phase modulation effect and consequent spectral phase correction. These efficient methods offer an opportunity to economically enhance existing laser facility intensities and offer a broader range of high-intensity physics to become more readily attainable. (paper)
