The CQC2T research laboratories at UNSW Canberra are located on the ADFA campus within the School of Engineering and Information Technology.
The Centre has access to three dedicated laser laboratories sharing an acoustically isolated foundation. Housed within these laboratories are three pneumatically isolated optical tables, two of which can be further isolated with compressed gas. One of the laboratories makes use of an infra-red Nd:YAG laser with feedback control of intensity noise (500mW CW @ 1064nm) as well as a visible, frequency-doubled Nd:YAG laser with feedback control of intensity noise (1W CW @ 532mm), which in turn drives an optical parametric amplifier. Another laboratory makes use of an infra-red fibre laser with feedback control of intensity noise (1W CW @ 1550nm) which drives a home-built second-harmonic generator and which, in turn, drives an optical parametric amplifier. The third laboratory makes use of a near-infra-red Titanium- Sapphire laser, with frequency and intensity noise control (2W CW @ 850nm). That laser will drive a home-built second-harmonic generator, which will drive an optical parametric amplifier. The optical parametric amplifiers are used as sources of nonclassical light in several subsequent experiments. There are also several infrared semiconductor lasers (10mW CW @ 1550nm) as well as free-space and telecommunications optoelectronics. The UNSW Canberra laboratories have an international reputation for their fast, quantum noise limited, linear photodetectors with associated electronics and they also make use of multiple infra-red single photon detector modules; as well as microwave digital and analogue test and measurement equipment. The inception of CQC2T has hailed some significant redevelopment in all the laser laboratories, with new temperature control systems, air-current control systems and pollutant-minimisation protocols all being instituted in 2011.
