The "Characterization laboratory for Nonlinear Quantum and Nano optics" (CNQN), a user facility installed in the ACP research bulding, consists from two main pillars. First, it hosts a multichannel fs laser system that provides simultaneously short pulse duration, highpower and a wide spectral coverage over different output beams. It comprises a Ti:Sa oscillator pumping two independently tunable optical parametic oscilators and a separate second-harmonic geneator, covering excitation wavelengths from 340 nm to 4100 nm wavelength. The second main component of CNQN is an array of single photon detectors enabling ultra sensitive detection in the visible and near-infrared spectral bands.This infrastructure enables researchers to perform experiments like pump-probe spectroscopy, nonlinear frequency mixing or the generation of quantum light on nanostructures that provide only very weak signals. It is thus ideally suited for fundamental research in nonlinear quantum-nano optics and is important tool to foster development of concepts for future applications in this field.

CNQN supported by the Thuringian State and the European Social Fund (ESF) and was put into operation at ACP in 2019/2020.
