Quantitative study of the destructive quantum-interference effect on coherent population trapping

Evelina Breschi, Georgy A. Kazakov, Roland Lammegger +3 more

We investigate experimentally and theoretically the coherent population trapping (CPT) effect occurring in $^{87}\text{R}\text{b}$ ${D}_{1}$ line due to the interaction with linearly polarized laser light ($\text{lin}\ensuremath{\parallel}\text{lin}$ CPT). In this configuration, the coherence is strongly influenced by the structure of the excited state; consequently, the quantum interference between dark states is an essential feature of this interaction scheme. We study the $\text{lin}\ensuremath{\parallel}\text{lin}$ CPT resonance as a function of the laser optical detuning. The comparison between experimental and theoretical results allows us to quantify the contribution from different dark states to the total signal. Based on these results, we investigate the signal depending on both the pressure broadening of the optical transition and the laser linewidth, and we find in which conditions the laser linewidth does not degrade the $\text{lin}\ensuremath{\parallel}\text{lin}$ CPT resonance.

Quasi-bichromatic laser for a lin⊥lin coherent population trapping clock produced by vertical-cavity surface-emitting lasers

Peter Yun, Bozhong Tan, Wei Deng +2 more

With two vertical-cavity surface-emitting lasers working under the master-slave sideband injection-locking configuration, we have realized a quasi-bichromatic laser beam with residual phase noise Δφ(2) < 0.282 rad(2). The two wanted frequency components share more than 96% power of the beam. With the realized beam, we have carried out coherent population trapping (CPT) resonance experiment with (87)Rb in the lin[perpendicular]lin CPT scheme, and recorded CPT resonance signal with contrast of 60%. Such laser system is promising to realize a lin[perpendicular]lin CPT clock with high performance and low power consumption.
