We describe calculations that predict and analyze distinctive features in the velocity distribution in 1D laser cooling for light shift potential well depths only a few times the recoil energy. These features can be interpreted in terms of populations of energy bands or even Bloch states in the periodic potential. They occur with a ${\mathrm{\ensuremath{\sigma}}}^{+}$ standing wave, with and without a small B field, and for lin\ensuremath{\perp}lin laser cooling. We have observed these features experimentally in a beam of metastable helium atoms cooled on the ${2}^{3}$${\mathit{S}}_{1}$\ensuremath{\leftrightarrows}${2}^{3}$${\mathit{P}}_{2}$ transition, with velocity resolution \ensuremath{\sim}0.3 recoil. |
