摘要： A superconducting single-photon detection system includes: a plurality of optical transmission paths through each of which a photon emitted from a light source is transmitted; a plurality of superconducting single-photon detectors (hereinafter referred to as "SSPDs") that are independent of each other and in one-to-one correspondence with the optical transmission paths; and a superconducting logic circuit that multiplexes first pulse signals output from the SSPDs. A photon entry time at which the photon enters each of the SSPDs through a corresponding one of the optical transmission paths is different for each of the optical transmission paths, and a difference in the photon entry time between the optical transmission paths is greater than a pulse width of a corresponding one of second pulse signals output from the superconducting logic circuit.

摘要： A laser pulse contrast ratio measurement device is presented, the device comprising a laser pulse generator for generating a sum frequency laser pulse, the laser pulse generator providing an interaction zone, a beam guide device having a first beam guide for guiding a reference beam to said interaction zone in said laser pulse generator and a second beam guide for guiding a probe beam to said interaction zone in said laser pulse generator. The device further comprises a detection unit for detecting the sum frequency laser pulse generated in said laser pulse generator. The probe beam has a probe beam frequency, whereas the reference beam has a reference beam frequency, wherein the reference beam frequency corresponds to the second harmonic of the probe beam frequency. The beam guide device of said device is adapted to direct the reference beam and the probe beam in a non-collinear manner under an interaction angle on said laser pulse generator so that the probe beam and the reference beam interact in the interaction zone of the laser pulse generator so as to generate the sum frequency laser pulse in the laser pulse generator, and wherein the beam guide device is adjusted to provide the interaction angle between the reference beam and the probe beam in the interaction zone in the laser pulse generator to be greater than 3°.

摘要： One aspect of the invention concerns a method for characterization of a light beam, comprising the following steps: - separation of the light beam by means of a separator optic into a first sub-beam and a second sub-beam; - propagation of the first sub-beam over a first optic and of the second sub-beam over a second optic, said first and second optics being respectively arranged so that the first sub-beam on leaving the first optic, referred to as the "reference beam", and the second sub-beam on leaving the second optic, referred to as the "characterized beam", are separated by a time delay τ; - recombination of the reference beam and the characterized beam by means of a recombiner optic, in such a way that the beams spatially interfere and form a two-dimensional interference pattern, the two-dimensional interference pattern extending along a first plane; - measurement of the spectral frequency of at least one part of the two-dimensional interference pattern by means of a measurement system, - calculation of the Fourier transform in the time domain of at least one spatial point of the frequency spectrum, said Fourier transform in the time domain having a time central peak and first and second time side peaks; - calculation of the Fourier transform in the frequency domain for one of said first and second time side peaks; - calculation of the spectral amplitude A
R (ω) and of the space-spectrum phase φ
R (χ,γ,ω) for said Fourier transform in the frequency domain.
