Here, the population transfer between two specific levels of Cesium atom under the influence of chirped laser source has been numerically investigated. The main goal of this study is the engineering of the population transfer between the 6 2 S 1/2 and 6 2 P 1/2 levels of Cesium which is corresponding to its D 1 transition line using a chirped laser source. Constructing the system Hamiltonian, as well as the initial and boundary conditions, the time-dependent Schrödinger equations are numerically solved and the population versus time for different physical parameters has been investigated. The final population of each state is calculated and discussed for changing the parameters such as laser intensity, laser frequency and chirping parameter. The results show that using the chirped laser source with tuned parameters, we can arbitrarily control the population of levels.
