We present a 10-petawatt class laser system based on the all OPCPA technique.The system mainly consists of 3-cascaded optical parametric amplifiers with LBO crystal and a grating compressor,a full width at half maximum (FWHM) duration of 18 fs was approached,with an energy of 91.1 J,corresponding to a laser power of 4.9 PW.
