I-VII: color of the sample in its LS state (I), HS state (VII), when the sample initially in its LS state within the hysteresis loop is excited at 355 nm by either a single (II), two (III), three (IV), four (V) and five (VI) nanosecond laser pulses. Fig. 1(VIII) shows the sample brought back in the LS state after photoexcitation.

(a) Normalized spectral changes of the sample reflectivity recorded after successive laser shots. The reflectivity changes have been normalized as explained in the text. (b) (◼) Thermal hysteresis loop deduced from the evolution of the sample reflectivity at 550 nm vs the temperature. The sample, set at a temperature of 328, 333, and 338 K, respectively, is excited by one (△), two (▽), three (○), four (◻), and five (◇) nanosecond pulses centered at (in grey) and (in black). The laser fluence on the sample is in both cases. The inset presents the absorption of the compound in the HS and LS states vs the wavelength.

Top: Path followed by the sample in the Temperature—high spin state Fraction phase diagram, after excitation by the first and the fifth laser pulse. Bottom: Evolution of the temperature (gray line) and the HS fraction (black line) of the sample after the first (dotted line) and the fifth (dashed line) laser shot.
