Analysis of Laser-Diode and Lamp Optical Pumping for a Rubidium Beam

The time evolution of populations of the ground state hyperfine Zeeman levels of ⁸⁷Rb atoms is analyzed using the Runge–Kutta method for the case that a rubidium beam is optically pumped, under different conditions of polarization, with a weak monochromatic laser and an ⁸⁷Rb lamp. On the base of the results above, the least estimated laser and ⁸⁷Rb lamp power for the best population inversion is obtained, aiding further investigations.
