The effect of temperature on absorbance of rubidium atoms in a vapor glass cell

Abstract

Glass cells containing neutral atoms are commonly employed in spectroscopy experiments and have potential applications in metrology. The temperature of the vapor plays a vital role as it directly influences the absorption rate of rubidium atoms. In this research, we study the effect of vapor temperature on the absorption spectrum of rubidium atoms. We observed the broadening of the spectral line and increased absorption, enabling us to determine the absorbance of atoms within the cell. These results provide valuable insights for our future work to characterize absorbance of homemade vapor cells for portable quantum device applications.
