Measurement of Sodium Vapor Densities in Optical Pumping Experiments using a Scanning Fabry–Perot Interferometer*

摘要: Reliable estimates of alkali vapor densities in the absorption cells used optical pumping experiments have usually been quite difficult to obtain. In present work, a pressure-scanned Fabry–Perot etalon has as high-resolution device obtain profiles from which density can be directly derived. The measurements made with sodium only, and results these are graphs optical-pumping signal strength Dehmelt transmission arrangement function density. These may useful estimating those for construction requisite spectroscopic equipment is not feasible.
