Paper Abstract

In this research, the effect of temperature on the absorption of rubidium vapor cell D2 line was studied by Two-photon absorption spectroscopy. The diameter and length of cylindrical rubidium vapor cell used in this research are 25.65 mm and 82.12 mm, respectively. The temperature of rubidium cell was varied from room temperature to approximately 80 °C using a peltier-thermoelctric module. The laser diode at 778 nm was used as a light source for two-photon absorption spectroscopy. The absorption spectra of rubidium D2 hyperfine transitions were recorded in the range of 200-1100 nm .The results show that the absorption peak at high temperature is higher than that of lower temperature.
