Webb22 mars 2012 · Abstract. Multipulse Ramsey-coherent population trapping (CPT) interference is implemented in a compact 87 Rb atomic vapor cell. With the addition of an acousto-optic modulator (AOM), a fully integrated vertical-cavity surface-emitting laser (VCSEL) is slaved to operate in pulsed mode with precise temporal control. Webb15 juni 2007 · Line-shape as well as amplitudes are analysed. For a double pulse excitation, the occurrence of probbability interference generates a Ramsey-fringe like resonance with a considerable narrowing of the central line. Such profile has been investigated as a function of the delay between pulses revealing a dependence of the fringes distribution. spotify podcast ratingWebb26 sep. 2024 · As intuitively expected from Fig. 2, the period of the Ramsey interference fringes reduces with N and the contrast of the fringes are nearly ideal. spotify podcast chart 2020
