Real-time probing of alignment and structural deformation of CS2 in intense nanosecond laser fields

A time evolution of the alignment and structural deformation processes of n eutral CS2 in intense non-resonant nanosecond laser fields (1.9 X 10(12) W/ cm(2)) is derived by ionizing CS2 using intense circularly polarized feinto second laser fields (5.5 x 10(14) W/cm(2)). From the real-time probing of t he momentum distribution of the resultant S3+ and C2+ fragment ions produce d through the Coulomb explosion induced by the intense fenitosecond laser f ields, it is identified that the alignment and the structural deformation p roceed simultaneously in the nanosecond laser fields.
