This internship will focus on the optical aspects of a setup that allows to program arbitrary shapes for a laser using holography techniques . The core apparatus is a Spatial Light Modulator (SLM), around which precision optics need to be setup. The goal is to obtain extremely focused (down the diffraction limit), arbitrary modes of coherent light. This setup will then be placed in a cryostat containing Copper Oxide samples cooled to 1 K, where the shaped light will be used to explore exotic states of excitons .
