Abstract

A time-dependent quantum wave packet method is used to calculate the branching ratio of photodissociation products of the HI molecule in two-color intense few-cycle laser pulses with varying relative phase. It is demonstrated that the relative phase between two intense few-cycle pulses ({omega} and 2{omega}) can be used for controlling the branching ratio of the photodissociation products I({sup 2}P{sub 3/2}) and I({sup 2}P{sub 1/2}) of the HI molecule. The nonadiabatic effect of the crossing potential energy curves on the photodissociation product yields of the HI molecule is also discussed.

Asymmetric branching of dissociated photofragments of HD{sup +} in an intense femtosecond laser field

Journal Article Chatterjee, Souvik; Bhattacharyya, S; Dutta, Bibhas - Physical Review. A

We have numerically explored the asymmetry in the branching ratio of the photofragments in the photodissociation of HD{sup +} (neutral D and neutral H), leading to the possibility of localization of the electron on a chosen nucleus by careful tuning of the laser parameters. For two different frequencies we show that, starting from an initial stationary wave function, proper tuning of the pulse duration (2{sigma}) and peak intensities (I{sup 0}) of the laser pulses can lead to very different branching ratios of the two reaction channels. The results are interpreted in terms of the propagation of the nonstationary wave packetmore »« less

Photodissociation of HI and DI: Polarization of atomic photofragments

Journal Article Brown, Alex - Journal of Chemical Physics

The complete angular momentum distributions and vector correlation coefficients (orientation and alignment) of ground state I({sup 2}P{sub 3/}2) and excited state I({sup 2}P{sub 1/} {sub 2}) atoms resulting from the photodissociation of HI have been computed as a function of photolysis energy. The orientation and alignment parameters a{sub Q}{sup (K)}(p) that describe the coherent and incoherent contributions to the angular momentum distributions from the multiple electronic states accessed by parallel and perpendicular transitions are determined using a time-dependent wave packet treatment of the dissociation dynamics. The dynamics are based on potential energy curves and transition dipole moments that have beenmore »« less

Branching and angular distribution of photofragments in two-frequency intense-field multiphoton dissociation of HD{sup +}

Journal Article Dutta, Bibhas; Sen, Sanjay; Saha, Samir; ... - Physical Review. A

We have investigated the branching ratios and angular distributions of photofragments resulting from the two-frequency multiphoton dissociation of HD{sup +} from initial bound level v{sub i}=0,J{sub i}=0 induced by linearly polarized parallel laser fields of equal intensity of 1 TW/cm{sup 2}. Both the laser frequencies {omega}{sub 1} and {omega}{sub 2} are below the dissociation threshold with {omega}{sub 1}<{omega}{sub 2}. We have used the time-independent close-coupling method. Molecular rotation has been taken into account with J=0-9 in each of the two electronic states GS and ES. The photon absorption channels (n{sub 1},n{sub 2}) with n{sub 1},n{sub 2}=0-3 have been included whenmore »« less

Nonsymmetric molecules driven by intense few-cycle laser pulses: Phase and orientation dependence of enhanced ionization

Journal Article Kamta, G; Bandrauk, A - Physical Review. A

The ionization of nonsymmetric heteronuclear diatomic molecules by intense few-cycle laser pulses linearly polarized along the internuclear axis has been investigated. It is found that enhanced ionization (EI) occurs in nonsymmetric molecules and is accompanied by enhanced excitation (EE). We show that the nonsymmetric distribution of the electron cloud between the two nuclei leads to a strong dependence of EI and EE on the carrier envelope phase of few-cycle pulses, and on the orientation of the molecule parallel or antiparallel with the peak electric field of the pulse. This effect is as strong as the pulse duration is short andmore »« less

Control of polarized iodine atom branching ratio in NaI photodissociation

Journal Article Hosseini, Babak; Sadeghpour, H; Balakrishnan, N - Physical Review. A

We report branching ratios between the ground and excited states of iodine atoms in the photodissociation of sodium iodide. We employ wave packet propagation techniques to study the optimal production of polarized iodine atoms and find experimentally realizable laser parameters to control the outcome. Application of a learning algorithm shows that the product branching can be controlled by suitably varying the time delay, the chirp, and the relative phase of the pump and control laser pulses. Periodic modulation of the polarized iodine atom branching ratio as a function of the delay between the firing of the two ultrashort laser pulsesmore »« less
