Fig. 1. Two types of targets and schematic diagram of the experimental setups. (a) The Type I target. (b) The Type II shot and the schematic diagram of the experimental setups. The silicon plate is set at the target chamber center (TCC), and two driven laser beams are focused on it. A crystal spectrometer is used to record the spectrum of plasma.
