a Time-resolved magneto-optical Kerr effect signal (open symbols) with single exponential fitting curves (dashed lines) for wavelength of pump pulse λpump = 800 nm. The values of FP pump fluence are written next to the experimental data. The data have shifted upwards for easy recognition. Error bars represent standard error of the avaraged raw data. b Remagnetization time τR with respect to fluence for λpump = 800 nm (square) and λpump = 800 nm (circle). Error bars represent standard error of the single exponential fitting.
