Optimizing the optical imaging system by \emph{in-situ} imaging the plugged hole in the ultracold atoms
Tianyou Gao, Dongfang Zhang, Lingran Kong +2
Optical absorption imaging has become a common technique for detecting the density distribution of ultracold atoms. The defocus effect generally produces artificial spatial structu…

Enhanced trapping of colding lithium by using the multiple-sideband cooling in a two-dimensional magneto-optical trap
Kai Li, Dongfang Zhang, Tianyou Gao +2
Trapping lithium with a big number in a simplified experimental setup has difficulties and challenges today. In this paper, we experimentally demonstrate the enhancement of \textsu…

Multiple Side-Band Generation for Two-Frequency Components Injected into a Tapered Amplifier
Hua Luo, Kai Li, Dongfang Zhang +2
We have experimentally studied the multiple side-band generation for two-frequency components injected into a tapered amplifier and demonstrated its effects on atomic laser cooling…
