Abstract

Laser frequencies were stabilized to the linear and saturated absorption spectral lines(LAS, SAS) in 87Rb vapors which were filled into two kinds of glass cell: cell A (87Rb vapor only) and cell B (87Rb vapor and buffer gases). The frequency shifts induced by the change of laser power density were −5 MHz/(mW/cm2) and −10 MHz/(mW/cm2) for cells A and B, respectively, when LAS was used. A frequency shift of −0.8 MHz/K was observed for cell B, which underwent a temperature change. However, such a temperature-induced shift was not observed for cell A. The highest frequency stability was 7.7 × 10−11 at a 70-s integration time.
