Dynamics of D slow dissociation induced by intense ultrashort laser pulses
Physical Review A—Atomic, Molecular, and Optical Physics, 2012•APS
The dissociation of D 3+ in intense ultrashort laser pulses is investigated using an improved
coincidence three-dimensional momentum imaging method that allows clear separation of
all fragmentation channels and the determination of the kinetic energy release down to zero.
Our results, using 10-fs, 790-nm pulses, suggest that a large peak at low kinetic energy
release is associated with the D++ D 2 dissociation channel of D 3+. The most likely
dissociation pathways leading to two-body breakup of D 3+ are identified with additional …

The dissociation of D in intense ultrashort laser pulses is investigated using an improved coincidence three-dimensional momentum imaging method that allows clear separation of all fragmentation channels and the determination of the kinetic energy release down to zero. Our results, using 10-fs, 790-nm pulses, suggest that a large peak at low kinetic energy release is associated with the D + D dissociation channel of D. The most likely dissociation pathways leading to two-body breakup of D are identified with additional measurements using 25-fs, 790-nm and 40-fs, 395-nm pulses. We also show that the slow D + D dissociation dynamics can be manipulated by the pulse duration.
