A Simple Demonstration of Optical Pumping Effect
Two sets of laser system are used, one as a probing beam, the other as an optical pumping beam, to analyze the population distribution of the magnetic sublevel. By scanning the frequency of the optical pumping beam at different frequency, the absorption spectrum is got, from which the population variation of some sublevel can be deduced.
