摘要：

The　ineffectiveness　of　powder　morphology　of　crystal　materials　for　laser　polarization　has　reached　a　consensus　in　almost　all　steady-state　experiments.　However,　in-depth　understanding　about　their　anisotropic　behavior　in　ultrafast　carrier　dynamics　is　still　lacking.　Here　we　systematically　explore　the　polarization　response　of　MAPbI3　powder　to　ultrafast　laser　based　on　two-color　pump-probe　transmission　technology.　The　isotropy　of　pump　polarization　and　the　anisotropy　of　probe　polarization　reveal　the　related　mechanism　of　the　interaction　between　ultrafast　laser　polarization　and　powder　materials.　It　provides　insight　into　the　ultrafast　photophysical　process　of　MAPbI3　powder　and　helps　to　develop　polarization-sensitive　and　ultrafast-responsive　optoelectronic　devices.　©　2023　SPIE.
