Laser cooling an ensemble of ultra cold atoms to quantum degeneracy or BEC. Have people accomplished this, and why do they want to do that instead of using evaporative cooling to reach BEC?


Laser cooling has successfully been used to achieve Bose-Einstein Condensation (BEC) in ultra-cold atomic ensembles, with compelling reasons to prefer it over traditional evaporative cooling techniques [1, 2, 4, 5, 16].
- Papers [1] and [4] demonstrate achieving BEC in rubidium atoms entirely through laser cooling, bypassing evaporative cooling and illustrating the efficiency of this approach, such as faster processes and reduced atom loss. These methods have shown potential applicability to multiple atomic species, suggesting broader implications for quantum studies. These papers specifically highlight advanced laser cooling techniques like Raman cooling in a crossed optical dipole trap and iterative optical lattice manipulation, enabling ultra-cold temperatures and high phase-space densities conducive to BEC [1, 4].

So far, I've closely analyzed 460 of the most promising papers, and I've found ~30-41 that are relevant, which is probably ~83.6% of all that exist.
To get this estimate, we do a statistical analysis of the discovery process.
