- Abstract
We measured the saturated absorption spectra of Kr I at 811.51 nm by using a titanium sapphire ring laser. Saturated absorption spectroscopy (SAS) is a simple and high-resolution spectroscopic technique. The hyperfine structure and isotope shift of the resonance lines were investigated by analyzing the 5s[3/2]
2 → 5p[5/2]3 transition observed in the saturated absorption spectra of Kr I. The King plot method was used to analyze the isotope shift composed of normal shift, specific shift, and volume shift. Based on this analysis, the unperturbed position of83 Kr relative to that of84 Kr was estimated to be 16.4 MHz. Furthermore, the magnetic dipole hyperfine constant A and electric quadrupole hyperfine constant B in the 5p[5/2]3 state were calculated to be A = −103.79(6) and B = −439.8(17) MHz, and those in the 5s[3/2]2 state were A = −243.88(8) and B = −454.4(13) MHz, respectively.
