YO laser cooling and trapping with an improved repumping scheme

ORAL

Abstract

Using a new repumping scheme for laser cooling of yttrium II oxide (YO), we have increased the photon scattering rate by 60{\%} on the cooling transition. With this improved cycling scheme, we have improved the number of slowed molecules (with velocity \textless 10 m/s) by 20 fold from a beam of YO from a single-stage cryogenic buffer gas cell. These molecules can be readily loaded into a radio frequency (5 MHz) magneto-optical trap. We will report the characterization of the MOT.
