Control of the photodissociation process of CsCl using a feedback-controlled self-learning fs-laser system

Ultrafast photodissociation assisted by strong non-resonant Stark effect: the ‘straddling’ control pulse

“…This is also the case with regards to experiments [5][6][7][8][9][10][11]. The simplest scenario of selective control in photodissociation reactions can be set in diatomic molecules, as in the first experiments validating the previous schemes [12,13] (or in more general terms, in polyatomic molecules when a single bond is broken).…”

Active control of product selection in a chemical reaction: a view of the current scene

“…Cs + Cl versus CsCl ! Cs + + Cl À , Feuer et al 31 have shown that the field that enhances the yield of ionic products that is obtained by an adaptive learning feedback process coincides with that calculated directly using the Tannor-Rice method. A demonstration that adaptive modification of the excitation field can be used to select between products of a branching reaction of a polyatomic molecule has been provided by Assion et al 32 They showed that adaptive modification of the phase distribution in a multi-femtosecond pulse permits selection of one or the other of two different bond breaking reactions of CpFe-(CO) 2 Cl, specifically, cleavage of one of the FeCO bonds to yield CpFeCOCl versus cleavage of both FeCO bonds and the FeCp bond to yield FeCl.…”

Bond breaking in light-induced potentials

“…[6][7][8] Although typically used in complex systems, learning control strategies 9 have also been applied to simple systems to help identify the underlying control mechanisms. [10][11][12][13][14] In this work, we shall study the control of photodissociation by dynamic Stark shift in the ICl − ion as the benchmark system. Using a single strong and resonant ultrashort laser pulse, which we call the pump pulse, the photodissociation spectra follows what is usually called a reflection principle.…”
