摘要:

在精细度为$1.8 \times 10^5$、模体积为1.3 $mm^3$的环形谐振腔内部形成具有铷原子的光晶格($^{85}Rb$)。我们通常在高达$10^{12} cm^{-3}$的密度和25至125 $μK$的温度下捕获几次$10^6$原子。尽管腔的带宽很窄(17.3 kHz),但由于腔内强度波动而产生的加热保持在较低水平,使得温度的时间演变由蒸发冷却决定。

英文摘要:

An optical lattice with rubidium atoms ($^{85}Rb$) is formed inside a ring resonator with a finesse of $1.8 \times 10^5$ and a large mode volume of 1.3 $mm^3$. We typically trap several times $10^6$ atoms at densities up to $10^{12} cm^{-3}$ and temperatures between 25 and 125 $μK$. Despite of the narrow bandwidth (17.3 kHz) of the cavity, heating due to intra--cavity intensity fluctuations is kept at a low level, such that the time evolution of the temperature is determined by evaporative cooling.
