Article Synopsis
  • This study presents a laser frequency stabilization technique aimed at enhancing laser cooling of potassium atoms by utilizing saturated absorption spectroscopy within the C-Band optical telecommunication range.
  • The research involved identifying and characterizing specific ro-vibrational transitions in acetylene (CH) that are crucial for targeting the potassium D1 and D2 cooling transitions due to a high-power second harmonic generation (SHG) stage.
  • The implemented laser system successfully cooled potassium isotopes using a 2D-3D Magneto-Optical Traps configuration.

We report on the observation of the coherent enhancement of the return probability ["enhanced return to the origin" (ERO)] in a periodically kicked cold-atom gas. By submitting an atomic wave packet to a pulsed, periodically shifted, laser standing wave, we induce an oscillation of ERO in time that is explained in terms of a periodic, reversible dephasing in the weak-localization interference sequences responsible for ERO. Monitoring the temporal decay of ERO, we exploit its quantum-coherent nature to quantify the decoherence rate of the atomic system.
