In this experiment, you will use the phenomenon of optical pumping to prepare an atomic gas in a highly polarized state, and also to detect changes in that polarization when you drive the atoms with a resonant radio-frequency magnetic eld.

An optical pumping primer

This pedagogical paper introduces the basic ideas of optical pumping. Some of the various optical pumping mechanisms are discussed, and illustrated by diagrams showing the experi- mental apparatus. The density matrix formalism is introduced and used to quantitatively examine the effects of optical pumping.

Optical Pumping

Optical pumping is a process in which light energy is used to excite electrons from a lower to higher energy level. It was first developed by Alfred Kastler in the early...

I Optical Pumping

By optical pumping, polarization of the spin vectors is produced, and macroscopic magnetization of the medium is obtained. The chapter states the principles of optical pumping and discusses the characteristics of the optical pumping methods.

Optical Pumping

The technique named "optical pumping" consists of absorbing pump light in order to excite erbium ions and provide population inversion in a given energy band. As seen in Figure 4.1, optical pumping may efficiently be performed around λ =0.98 μm from the fundamental ground state level 4 I 15/2 into the 4 I 11/2 level.

Theory

Thankfully, through the process of optical pumping, we can simplify our problem by transferring a sizeable fraction of our population to the states of interest. Optical pumping relies on the use of light to manipulate the internal degrees of freedom of our atoms.

OPTICAL PUMPING

In this article we shall he concerned with the pumping of individual atoms from lower to higher states of internal energy. The word optical refers to the light energy that is the source of power for the pump. Why pump atoms? The purpose is to prepare them for a …
