As promised, we are back with a green MOT! While careful optimization is still needed, we are happy to report that we have now obtained a green MOT of 174Yb atoms. We are able to switch among different Yb isotopes with ease, so a 171Yb MOT is also in the workings. In the meantime, here is an absorption image of about 2 million trapped Yb atoms. While optimizing the green MOT we are planning the next steps to trap atoms in optical tweezers! |

We have achieved a blue MOT of 174Yb atoms! Due to service jobs being done to our 556 nm green laser, we have decided to get the setup ready for a blue MOT instead. Once our green laser will be operational again, we’ll steer towards making a green MOT directly, through the aid of a blue crossed-slowing stage. |

We have finished assembling and baking our vacuum system, which is now ready to host laser cooled Yb atoms! |

Our atomic source has arrived, as well as the first lasers, and testing is underway! Special thanks to Yb lab for the hospitality. |
