Title: Laser waveform control of molecular dissociation and field-free
orientation
Time: Today, 10.15 (N.B.)
Place: Fysisk Auditorium
Abstract:
The control of
the electric field waveform of laser light opened the door for the direct
manipulation of electron dynamics in atomic and molecular systems. For
frequencies in the range of visible light this waveform changes on an
attosecond timescale. Waveform controlled few-cycle pulses and femtosecond
two-color laser fields have been used to control electron localization in the
dissociative ionization of molecular hydrogen. Together with an introduction to
these prototype studies, new results on the attosecond control of electron localization
in multi-electron molecules and the application of femtosecond two-color laser
fields in field-free orientation of heteronculear molecules will be presented.
