(a) Evolution of the normalized vector potential of a laser pulse propagating through the 10-mm long plasma medium and (b) electron energy spectrum after the medium obtained from quasi-cylindrical 3D PIC simulations CALDER-Circ. The blue line indicates the results obtained with the fast-rising, negatively chirped laser pulse with GDD of −400 fs2 and TOD of +5000 fs3. The red line is for the slow-rising, positively chirped laser pulse with GDD of +450 fs2 and TOD of −7000 fs3. The pulse duration in FWHM was 59 fs for both cases.
