WebSub-Doppler cooling techniques have been developed for potassium, but dipole trap loading remains inefficient due to the low initial density. To this end, we have developed and built a trapping field using an octupole magnetic field, which combines elements of both near-zero fields at the trap center for sub-Doppler cooling, and restoring ... WebRaman sideband cooling in a 1D lattice is shown to produce clouds with phase space densities of about 0.1, which is significantly larger than that achieved in previous work, but still shy of quantum degeneracy. Raman sideband cooling in a 2D lattice is shown to lead to nonthermalized clouds when the atom number and trap frequencies are ...

WebSep 19, 2024 · We report on vibrational ground-state cooling of a single neutral atom coupled to a high-bandwidth Fabry-Pérot cavity. The cooling process relies on degenerate Raman sideband transitions driven by dipole trap … Raman sideband cooling is a method to prepare atoms in the vibrational ground state of a periodic potential and cool them below recoil limit. It can be implemented inside an optical dipole trap where cooling with less loss of trapped atoms could be achieved in comparison to evaporative cooling, can be implemented as a mid-stage cooling to improve the efficiency and speed of evaporative cooling, and is generally extremely insensitive to the traditional limitations of laser c…
