Vibration measurements on cold plate of attoDRY800
The interferometric measurements to the left show vertical & horizontal dis-
placement data measured directly on the cold plate of the attoDRY800. The
peak-to-peak vibrations in vertical direction are around 3 nm (4 nm), while in
lateral direction they are around 2 nm (17 nm) in a bandwidth of 200 Hz (1500
Hz). This very efficient and unique low vibration design even allows for very
sensitive optical measurements such as optical probe stations or high resolu-
tion optical spectroscopy on nanostructures.

Dr. Heindel
Our group is working on quantum optics experiments exploiting deterministic quan-
tum light sources based on semiconductor quantum dots. The two attoDRY800 systems
will be used to probe the mututal two-photon interference of remote quantum emitter
located in both cryostats. We are keen on the exciting experiments possible with these
very stable cryostat systems.

The FFT of the data above is shown to the left as well for
both directions, vertical and horizontal respectively, at a
bandwidth of 1500 Hz. The dashed line at 1 pm indicates the
noise floor of the interferometer.
