Abstract

Detailed measurements of sub-Doppler cooling of ⁸⁷Sr in a single-stage ¹S₀-¹P₁ MOT were performed for the first time. Cooling dynamics associated with trapping beam intensity, detuning, atom density, and the trap loading times were carefully explored. The results demonstrate a MOT temperature for ⁸⁷Sr that is clearly below the Doppler limit and is strongly dependent on the trapped atom number and cooling beam intensity.
