Fig. 1. Schematics of the front-end system of the SG-III facility where the shaped pulse is generated.

Fig. 2. Whole process of how the SG-III facility achieves the required tripled waveform.

Fig. 3. (a) Objective ultraviolet waveform and the corresponding fundamental waveform; and (b) the simulated initial input waveform in the injection laser system.

Fig. 4. (a) Schematics of the experimental setups; (b) the pulse shape in the preamplifier; (c) the fundamental and (d) the tripled pulse shapes. The dashed lines show the details of the pulse foots.

Fig. 5. Waveform comparison between the two main shots. The solid lines give the whole waveforms, while the dashed lines give the details of the foot.
