Abstract

We report on a systematic study of the loading efficiency and confinement for both continuous-wave and pulsed dipole force traps of equal average power. A protocol for optimal loading in each case will be presented.

Funding Information:
As a precursor to the FEL experiments, we are investigating the loading efficiency of a FORT produced by a pulsed Nd:YAG laser in direct comparison to a continuous-wave Nd:YAG laser FORT of comparable average power. In particular, we have studied how the transfer of ultracold rubidium atoms from a magneto-optical trap (MOT) to the FORT depends on loading time, MOT laser detuning, and hyperfine repumper intensity. For example, in figure 1 below, we show the percentage of atoms transferred from the MOT to a pulsed FORT with 7W of average power versus the FORT loading time. We have also investigated the confinement time of atoms in the FORT for different average FORT powers. To date, we have found both similarities and differences in the optimal parameters for FORT loading of a continuous-wave vs. a pulsed FORT. Among our findings are that the loading and confinement times for the two types of traps are nearly the same, however, the FORT loading dependence on MOT detuning (during the loading phase) is very different for cw vs. pulsed traps. We will present a detailed report of our experimental results. Supported in part by the National Science Foundation, Grant no. INT-0225869, KOSEF, Jefferson Lab, and Old Dominion University.
