Evolution of the bubble velocity. Part (a) shows the variation of the (normalized) velocity of the back of the bubble, \(\beta _b\) for the single pulse (- - -), double pulse (—), and higher-intensity single pulse (\(\cdot\) −) configurations, with the highlighted region expanded in part (b). Part (c) shows the variation of the (normalized) velocity of the dephasing point at the centre of the bubble, \(\beta _d\). Data presented in Fig. 6c for the single pulse LWFA (- - -) originally appeared in Yoffe et al.44.
