In order to conduct quantum simulation with ultracold trapped Lithium-6 atoms, a multitude of optical elements is needed. By dividing our setup into modules that can be easily moved and exchanged, we hope to become more efficient both in implementing new setups and tweaking existing ones. Additionally, reducing degrees of freedom as much as possible will yield more stable alignments.
Examples for this passive stability are our double pass modules for acousto-optic modulators, which are used to detune a cooling and a repumping beam.
The first cooling stage of the experiment is a 2D-MOT. As available laser power is crucial for a fast loading rate, we use a bowtie configuration and prepare flat-top beam profile using an optical diffuser. We use a high-power TA-SHG laser system providing 1W of laser power.
This Laser is locked to the Lithium-6 D2 transition using a modulation transfer scheme to ensure minimal drifts in frequency.
