State-selective excitation of atoms or molecules in laser pulse fields
V.Savva, A.Mazurenko, and Z.Dolya
The coherent mechanism of ultrafast state-selective excitation of atoms and molecules is presented by a theoretical simulation. To excite a molecule into a target vibrational level high-power picosecond pulses are necessary in the infrared area. This mechanism can be used to excite an atom in the target state by subpicosecond laser pulses in the visible region. Some pulses with different frequencies and powers can be used to reach a target.
