Times Cited Count：0 Percentile：0.01(Astronomy & Astrophysics)Regarding rovibrational transitions of diatomic alkali haride molecules, optimal waveform of laser electric field was calculated on the basis of the optimal control theory. In this study, we implemented the polarizability term into the Hamiltonian, which defines the field-molecule interaction. As a result, we obtained waveforms causing both one- and two-photon processes in a relatively high electric field regime, while waveforms causing only one-photon process was observed in a weak filed regime as well as the previous study. These results imply that the effect of two-photon process is successfully taken into account in the optimal control theory calculation. Now we can expect more reliable calculation even for strong laser field.

Electric field of laser pulses is designed by the optimal control theory. The target process is isotope-selective rovibrational excitation of two isotopologues of the lithium chloride molecule, Li
Cl or Li
Cl. The calculation includes both radial and angular motion of atoms in molecule. As a result, it is found that a laser pulse field which can cause isotope-selective rovibrational excitation with high yield exists.

Optimal control theory calculations are performed to investigate the possibility of isotope-selective ro-vibrational excitation of diatomic molecules. In the present calculation, rather strong laser field is applied. Consequently, in the given field strength, it has been found that two-photon excitations mainly proceed and that Raman process and one-photon process are minor processes. The final yield of the isotope selective ro-vibrational excitation is 0.6 - 0.9.
