This work reports the successful implementation of a fiber-based laser transmitter on an already existing astronomical platform. To measure the time of flight for satellite laser ranging applications, pulse energies of a few 10 μJ are sufficient. Op

We report on our progress towards realization of a toroidal trap for Bose-Einstein condensates (BECs) of 87Rb using a time-averaged optical dipole potential. To achieve BEC we utilize a 20 W laser operating at 1064 nm to form an optical dipole trap i

Specifically tailored potentials can potentially be helpful tools when investigating properties of ultra-cold gases. In this paper we study the superfluid critical velocity of Bose-Einstein condensates. Previous experimental investigations have gathe
