Kurzbeschreibung
This is an optical cryostat to perform experiments on semiconductor quantum dots for the generation of multiphoton states. It is a closed cycle system with a user friendly computer control and can be operated in a turn key fashion. The base temperature of the cryostat is 3.7K and it is equipped with a 3-axis nanopositioner system and multiple optical accesses. The cool down time is approximately 6 hours. It can be used to perform high sensitive quantum optics experiments and can function as a shared facility for other potential users.

Methoden & Expertise zur Forschungsinfrastruktur
It can be used to perform quantum optics spectroscopy on semiconductor quantum dots, 2D materials, defect centres etc.
The cryostat has to be operated together with a laser system to probe the sample and a sensitive spectrometer or other single photon sensitive detectors like APDs or SNSPDs to detect the signal.
