population change in the fine structure levels of cesium atoms using chirped laser

Here, the population transfer between two specific levels of cesium atom under the influence of chirped laser source has been numerically investigated. the maingoal of this study is the engineering of the population transfer between the 62s1/2 and 62p1/2 levels of cesium which is corresponding to its d1 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.
