a Kinetic at 406 nm with different pump fluence. b \({{{{{\rm{ln}}}}}}\left(n\right)-{{{{{\rm{ln}}}}}}({n}_{0})\) vs.\((t-{t}_{0})\). c \(1/{n}^{2}-1/{n}_{0}^{2}\) vs.\((t-{t}_{0})\), and d \(1/{{{{{\rm{n}}}}}}-1/{{{{{{\rm{n}}}}}}}_{0}\) vs. \((t-{t}_{0})\) with different pump fluences, with the inset corresponding to this plot under 0.13 mJ/cm2. The red dash lines represent their linear fits. In a–d, different symbols denote corresponding data obtained under different pump fluences, i.e., 0.13 mJ/cm2 (black square), 0.64 mJ/cm2 (red circle), 1.27 mJ/cm2 (green up triangle), 1.91 mJ/cm2 (blue down triangle), and 2.54 mJ/cm2 (cyan diamond).
