Hyperfine measurement of $6{\text{P}}_{1/2}$ state in ${}^{87}\text{Rb}$ using double resonance on blue and IR transition

Abstract

In this paper, we present the spectroscopy of 6P${}_{1/2}$ state in ${}^{87}$Rb using double resonance technique at $780\text{nm}$ and $421\text{nm}$. The double resonance technique is implemented using electromagnetically induced transparency (EIT) and optical pumping methods. Using these spectroscopy methods, we have measured the hyperfine splitting of 6P${}_{1/2}$ state with precision of $<$400~kHz which agrees well with other spectroscopy methods such as electrical discharge and saturated absorption spectroscopy at $421\text{nm}$.
