In his masters thesis "Optical dipole trap for a caesium Bose-Einstein condensate" he built and characterized the setup for the dipole trap in which the BEC will be created. Two focused laser beams cross orthogonaly under the atom chip, creating a lens shaped potential for trapping atoms. The high power beams stem from a 50 W high power 1064 nm fiber laser whose output is mode cleaned using a pinhole filter and split. After splitting each beam is power modulated by two detuned acousto optic modulators and coupled into a high power single mode fiber connected to the experimental setup.
Now Max reinforces the Caesium Team for his PhD - Congratulations!
