Abstract

Abstract We theoretically investigate the complete population transfer among quantum states of the N a 2 molecule using ultrashort pulse trains using the time-dependent wave packet method. The population accumulation of the target state can be steered by controlling the laser parameters, such as the variable pulse pairs, the different pulse widths, the time delays and the repetition period between two contiguous pulses; in particular, the pulse pairs and the pulse widths have a great effect on the population transfer. The calculations show that the ultrashort pulse train is a feasible solution, which can steer the population transfer from the initial state to the target state efficiently with lower peak intensities.

Steering population transfer between electronic states of the Na 2 molecule beyond the rotating wave approximation

Yong‐Chang Han

Abstract By utilizing the time-dependent wavepacket method, we studied the population transfer between the electronic states of the Na 2 molecule driven by femtosecond laser pulses. Three electronic states, X 1 Σ g + , A 1 Σ u + and 2 1 Π g , are taken to be the initial, the intermediate and the target states, respectively. Two classes of calculations are performed for comparison: one is to invoke the rotating wave approximation (RWA), and the other is more accurate calculations without consideration of RWA (non-RWA). It is found that for this three-state-model, the RWA fails to describe the accurate population transfer process in femtosecond-pulse fields and that the adiabatic passage is hard to be constructed in the non-RWA calculations. Based on the non-RWA calculations, we determined a set of laser parameters, including the peak intensity, detuning, pulse duration and time delay, for efficient population transfer.

Quantum control of dressed state population for Li 2 molecules by intense femtosecond laser pulses

Xiao Han, Wei-Shen Zhan, Shuo Wang +2 more

Abstract We investigated the Autler–Townes splitting in photoelectron spectra of molecules steered by ultrashort laser pulses using the time-dependent wave-packet method. Structure of the Autler–Townes splitting was presented to analyze the information of a selective population of the dressed states. It was found that population transfer process, structure of photoelectron spectrum and pattern of Autler–Townes splitting can be controlled by adjusting the intensity, wavelength and delay time of laser pulses.

Controlling Population Transfer and Dissociation Rate of Na 2 Molecules with Ultra-Short Intense Laser Pulses

Kai‐Jun Yuan, Senming Wang, Shu‐Lin Cong

A scheme used for controlling the population transfer and the dissociation rate of Na 2 molecules is described by using the quantum wavepacket dynamical method. It is theoretically shown that the population transfer and the dissociation rate of Na 2 molecules can be controlled by pump and probe laser pulses with appropriate widths of pulses, sequence and intensities.

Complete population transfer to and from a continuum and the radiative association of cold Na atoms to produce translationally cold Na2 molecules in specific vib-rotational states

Amichay Vardi, M. Shapiro, Klaas Bergmann

We demonstrate the feasibility of a laser induced complete population transfer to and from a continuum of states. We study the two-photon dissociation of v = 28; J = 1,...,10 sodium dimers. We demonstrate that using just a pair of "counter intuitively" ordered pulses we can dissociate 100% of the molecules in an ensemble. The scheme is shown to be stable with respect to the initial choice of rotational level and to fluctuations in the laser frequency and intensity. We also study the reverse phenomenon of complete population transfer from the continuum. We perform calculations on the radiative association of Na atoms to form the Na2 molecule in specific vib-rotational states. It is shown that two pulses of 20 nsec duration and as little as 6 MW/cm 2 peak power can photo-associate more than 98% of the atoms within a (pulse and velocity determined) relative effective distance, to yield Na2 molecules in the chosen v = 28; J = 10 vib-rotational state. This means that given a density of 10 16 atoms/cm 3 and a temperature of 7K, a 10Hz pulsed laser source of the above parameters can con- vert half of all the Na atoms in the ensemble to v = 28; J = 10 Na2 molecules within 15 seconds of operation.

Population transfer of a NaH molecule via stimulated Raman adiabatic passage

Jing-Bo Zai, Wei-Shen Zhan, Shuo Wang +2 more

Abstract The population transfer of a NaH molecule from the ground state X 1 Σ + to the target state A 1 Σ + via stimulated Raman adiabatic passage (STIRAP) is investigated. The results show that the intensity, delay time and detuning have a significant effect on population transfer. A large population transfer is observed with increased pump and Stokes intensity, especially when the pump and Stokes intensity match. Population transfer also depends on the delay time between the pump laser pulse and the Stokes laser pulse. The detuning of the two pulses influences the population transfer. Efficient population transfer can be realized under the resonant or two-photon resonant condition.

Selective and efficient excitation of diatomic molecules by an ultrashort pulse train

Luı́s E. E. de Araujo

In this paper, I discuss the selective and efficient vibrational population transfer between electronic states of diatomic molecules by a weak, ultrashort pulse train. The spectrum of each individual pulse in the train is wide enough to simultaneously excite several vibrational levels of the molecule. However, selectivity is achieved by mismatching the frequency comb, associated with the pulse train, to the excited vibrational levels. Efficiency results from the coherent accumulation of population from one pulse in the train to the next.
