In the summer of my freshman year, I worked at Professor David Hall's lab on testing an optical system for Bragg scattering of atoms for real time imaging of optically trapped Bose-Einstein condensate. The project involves aligning optics and acousto-optic modulators, working with laser mounts, spectrum analysers and other associated electronics.
I continued to work at Professor Hall's lab in Fall 2011 semester, transferring this system onto the main apparatus in the lab.
