AI 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.
Article Abstract
We demonstrate a laser frequency stabilization technique for laser cooling of potassium atoms, based on saturated absorption spectroscopy in the C-Band optical telecommunication window, using ro-vibrational transitions of the acetylene molecule (CH). We identified and characterized several molecular lines, which allow to address each of the potassium D2 (767 nm) and D1 (770 nm) cooling transitions, thanks to a high-power second harmonic generation (SHG) stage. We successfully used this laser system to cool the K isotope of potassium in a 2D-3D Magneto-Optical Traps setup.
