a Time evolution of Ne under 400-nm pump with different pump fluences. b Ne and its second-order rate equation fit (zooming in the inset) for 83 μJ/cm2 within 20–1000 ps. c, d Ne and its third-order rate equation fit in the inset for 42 and 14 μJ/cm2 within 20–1000 ps. The fitted curves in the insets are extrapolated to short time delays. Error of Ne is calculated via Eq. (8) according to propagation of error.
