- Аннотация: The conditions for the generation and detection of quantum-correlated pairs of optical and terahertz photonsin the process of strongly frequency-nondegenerate parametric down-conversion of light are investigated. Anapproach based on increasing the frequency of the optical pump is proposed, whereby the power of a weakflux of terahertz idler photons can be measured for a wide range of parametric gain coefficients, down to theonset of the spontaneous down-conversion regime, using the same terahertz detector with a limited dynamicrange. It is shown experimentally that the doubling of the frequency of pulsed laser pump leads to a 5-foldreduction in the lowest value of parametric gain that is still sufficient for detecting terahertz idler photons witha cooled hot-electron bolometer.
