Point spread function of one of our objectives imaged using a star target and a wavelength of 556nm

Our custom-made high NA microscope objectives neccessary for trapping and manipulation of neutral Yb atoms at various different wavelengths have been extensively tested and perform to specs. More details can be found in the Bchelor thesis of Jan Philip Deppe.

Single Fermionic Yb atoms in optical tweezers

After successful optimization of trapping and imaging of individual bosonic 174Yb atoms we have now succeeded in trapping fermionic 173Yb atoms in triple (1S0, 3P0, 3P1) magic optical tweezers at 759nm using the magic angle for the polarization of the tweezer light.

First single Yb atoms in optical tweezers in Hamburg!

For the first time we have loaded individual 174Yb atoms in a small tweezer array at a wavelength of 532nm. Atoms are imaged on the 1S0 -3P1 transition.
