摘要：

We demonstrate laser Doppler cooling of magnetically trapped neutral atoms. Following the application of one-dimensional optical molasses to a sample of magnetically trapped Na atoms, a substantial reduction has been observed in the linewidths of both laser absorption and rf resonance spectra, indicating cooling of the sample to approximately 2 mK. A simple model of the one-dimensional Doppler cooling process of the atoms in the trap is presented and compared with the experimentally observed results.
