This system has the advantage of having very high photon count rates, it can simulate a large range of pump beam profiles simply by modifying the hologram on the SLM, and it can be easily converted to a SPDC setup by simply changing only two of its components without the need to perform realignment. This setup can be used to give an indication whether a SPDC experiment will be feasible in a very short amount of time.enQuantum opticLaser beam shapingOptical angular momentumQuantum state engineering and measurementsSpontaneous parametric down conversionSpatial light modulatorsConference PresentationZhang, Y., McLaren, M., Roux, F., & Forbes, A.
