Abstract The post-compression technique based on self-phase modulation of high-energy pulses leads to an increase in achievable peak power and intensity. Typically, the considered experiments have been less than 100 fs duration. Here, method is applied ELFIE laser system at LULI facility, for a pulse 7 J energy initial measured duration 350 fs. A 5-mm-thick fused silica window 2 mm cyclic-olefin polymer were used as optical nonlinear materials. 9 cm diameter beam was spectrally broadened...
