摘要: Abstract Population transfer between the fine structure levels of cesium atom is numerically investigated when a linearly chirped Gaussian pulse interacts with atom. For this purpose, time-dependent Hamiltonian quantum system developed and Schrodinger equation solved. In result transition probabilities are obtained discussed towards precise controlling dynamics. The results show that for both single-pulse multi-pulse cases, probability final population distribution can be flexibly controlled by optimal adjustment laser parameters. addition, it shown increase increasing duration in single case as well number pulses system.
