摘要：
Ultrafast deformation of geometrical structure of CO2 in an intense laser field (1.1 PW/cm(2) = 1.1 X 10(15) W/cm(2)) was investigated by momentum imaging of the fragment Op+ and Cq+ (p, q = 1-3) ions produced from CO2z+ through the Coulonnb explosion processes, CO2z+ --> Op+ + Cq+ + Or+ (z = p + q + r). The observed large mean amplitude along the angle O-C-O bond angle (similar to 40 degrees) was attributed to the ultrafast bending motion induced on the light-dressed potential energy surfaces.
