Paper Abstract

We demonstrate the spectra of 87Rb 5S1/2 - 5P3/2 - 4D3/2 transitions by utilizing the double-resonance optical-pumping (DROP) and optical-optical double-resonance (OODR) techniques, respectively. The DROP spectrum, compared with the traditional OODR spectrum, show a much better signal-to-noise ratio (SNR). Paying special attention to the influence of alignment of lasers where the coupling and probe beams are counter-propagation and co-propagation on DROP spectrum, so as to further narrow the spectral width by means of electromagnetically induced transparency (EIT). When -the frequency of 1.5μm fiber-pigtailed butterfly-type distributed-feedback (DFB) diode laser is stabilized to the DROP spectrum of 87Rb 5P3/2 - 4D3/2 transition, the preliminary result of residual frequency jitter after stabilization is ~ ±1.3 MHz within 60 s.
