ApplicationCaesium Spectroscopy - D2 Line
Caesium is a very reactive alcali metal of the first group of the table of elements. It was first discovered by Bunsen and Kirchhoff in 1860 using spectroscopic investigations. It is characterized by one valence electron.
The spectra show the saturated absoption of the D2 line of Caesium at 852nm. The spectra are detected with a continuous scan with a Sacher Lasertechnik tunable diode laser system.
