Optical Pumping of Lithium 6 Atomic Beam

Optical pumping plays the main role in slowing atoms in Zeeman slower, which provides the opportunity of interacting with atoms for longer time because of energy level shift. For better deceleration it is essential to change the state of atoms in the beam to the state with the greatest projection of total atomic angular momentum, that is where pumping plays a great role. This will allow to increase the number of trapped atoms in future experiments. Numerical modeling showed approximate time for the system to enter the steady state and approximate number of atoms, which are being pumped at fixed laser frequencies. Also, it showed dynamic change of the system in the process.
