Australian National University Facilities
The Australian National University Node has four CQC2T experimental laboratories located at The Department of Quantum Science and The Laser Physics Centre within The Research School of Physics and Engineering.
The solid-state spectroscopy laboratory is equipped with a range of laser sources and cryogenic equipment for performing spectroscopy of solids. There are a number of dye-laser systems, having wavelength tuneable over a wide range, and offering sub-kilohertz resolution by locking to an external reference cavity. There is a nitrogen pulsed laser pump available for low-resolution spectroscopy, and a diode laser system operating at telecom wavelength. There is a range of cryostats available, including continuous flow, bath, and bucket designs.
The quantum memory laboratory contains a range of state of the art laser equipment. There are 4 ultra-stable vibration isolated optical tables each dedicated to different aspects of probing atomlight interactions. There are two highly tuneable titanium-sapphire lasers that are used to generate both the fields needed to manipulate our atomic ensembles as well as pump a source of nonclassical light.
The quantum communication laboratory contains 3 large ultra-stable and vibration isolated optical benches in a temperature controlled dust proof room. The laboratory contain many state of the art laser sources, including two frequency doubled Innolight Nd:YAG lasers producing beams at 1064nm and 532nm, one ultra-stable Innolight Nd:YAG laser at 1064 nm, one Toptica tunable diode laser producing light from the visible spectrum to the near infrared as well as a NP Photonics fibre laser source at 1550nm.
The Ultra-Precision Lathe Facility at the ANU can custom machine metal and certain classes of optical crystals to optical grade precision. The facility houses a Moore Nanotech 250 UPL lathe with a stiff air-bearing spindle. Depending on the material and the complexity of the form, surface smoothness of up to λ/50 may be attainable. The lathe has precision 4 axes control and can fabricate non-cylindrically symmetric optical components with size ranging from tens of micrometres to tenths of centimetres.
