Note: Investigation of atom transfer using a red-detuned push beam in a double magneto-optical trap setup

Surjya Prakash Ram, Satya Ram Mishra, S. K. Tiwari +1 more

We present our results on transfer of cold (87)Rb atoms from a vapor cell magneto-optical trap to ultrahigh vacuum magneto-optical trap (UHV-MOT) using a red-detuned continuous wave push beam in a double-magneto-optical trap setup. We find that use of retro-reflected red-detuned push laser beam results in higher number in UHV-MOT than the number obtained without retro-reflection of push beam.

Enhanced atom transfer in a double magneto-optical trap setup

Satya Ram Mishra, Surjya Prakash Ram, S. K. Tiwari +1 more

We report the observation of significant enhancement in the transfer of laser-cooled $^{87}\text{R}\text{b}$ atoms between two vertically separated magneto-optical traps (MOTs) when an appropriately tuned and aligned hollow laser beam was used. In the experimental setup, the lower MOT was loaded from a continuous flux of atoms ejected from the upper MOT by a resonant push beam. The observed enhancement appears to be mainly due to a slowing down of atoms by the hollow beam after being ejected from the upper MOT.
