| Abstract: | Phase and polarization control of photochromism in the solid phase is experimentally demonstrated. Photochromism initiated by a two-photon absorption of femtosecond laser pulses in a three-dimensional solid-phase polymer sample of spiropyran is controlled by varying the polarization state and the chirp of laser pulses. |
