Excitation of an atom in target state by high-power pulses of laser radiation

摘要

Abstract: In principle, a possibility has been shown to excite an atom on the target level selectively and very fast with the use of high-power laser pulses. For this aim the effect of ultrafast selective excitation which was revealed earlier for vibrational levels of a molecule can be used. The example Li atom is considered. Some pulses with different frequencies should be used to excite an atom on high energy levels. !7
