Femtosecond two-photon absorption phase change spectroscopy of a ZnSe single crystal

We measured time- and frequency-resolved phase changes owing to two-photon absorption induced by ultrashort (10   fs) pulses transmitted through a transparent material (ZnSe crystal), using femtosecond two-photon phase change spectroscopy. The maximal phase change was 0.02   rad when a ...
