a Normalized TDR signal S(t) decay dynamics at probe photon energy of 0.24 eV. b Maximum TDR signal S(0) against pump fluence intensity PFL and incident photon density \({I}_{{{{{{\rm{P}}}}}}}\). c Inverse TDR profile fitted with the analytical model of 1/S(t), shown on top of (c, d), to obtain slope and intercept plot in d. In b–d, the black dotted lines correspond to respective linear fits. The arrow direction in (a, d) represents increase in PFL. Source data are provided as a Source Data file.
