Abstract
The spectra of cesium 6P3/2 - 8S1/2 excited-state transition have been obtained using double resonance optical-pumping (DROP) technique in a room-temperature vapor cell, and have shown a much better signal-to-noise ratio (SNR) compared with that using the traditional optical-optical double resonance (OODR) method. Furthermore, the line-width of DROP spectra is obviously narrowed by electromagnetically-induced transparency (EIT) effect in cesium 6S1/2 F=4 - 6P3/2 F'=5 - 8S1/2 F''=4 transitions. Finally, such DROP spectrum of 6P3/2 F'=5 - 8S1/2 F''=4 transition with a high SNR and a narrow line-width is applied into frequency stabilization of a 795 nm external-cavity diode laser, and the residual frequency fluctuation is ~ 600 kHz within 500 s.
