Review of methods for time interval measurements with picosecond resolution

نویسنده

  • Józef Kalisz
چکیده

This paper is a review of methods and techniques used for precise measurement of time intervals (TIs) or precise conversion of TIs to digital data. The following methods are described: the counter method and averaging, time stretching, time-to-amplitude conversion followed by analogue-to-digital conversion, the Vernier method, conversion utilizing tapped delay lines, and interpolation methods. Special attention has been paid to converters utilizing integrated delay lines for digital conversion of TIs, including designs with phase-locked loop and delay-locked loop circuits. This review is illustrated by design examples and contains a comprehensive list of references.

Determination of the Shape and Duration of Picosecond Light Pulses by Bleaching of Dyes

The knowledge of the duration and shape of picosecond light pulses is essential in time resolved picosecond studies. Various techniques for the measurement of picosecond pulse durations are summarized in recent reviews [1,2,3]. The most widely used methods are the two-photon-fluorescence technique (TPF) [4], the non-collinearly phasematched second harmonic generation (SHG) [5], the Kerr shutter...

Review of Chromatic Dispersion Measurements Techniques

Chromatic dispersion measurements require experimental conditions which meet with particular difficulties, that is, a wide spectral coverage and a picosecond time resolution over a kilometer-length fiber. This paper shows what makes of these measurements an experimental challenge and the main solutions found since the tate seventies are reviewed. Pulse propagation, interferometric and phase-shi...

Experimental characterization of picosecond laser interaction with solid targets.

We have characterized the plasma produced by a picosecond laser pulse using x-ray spectroscopy. High-resolution high-sensitivity spectra of K -shell emission from a Ti plasma have been obtained, showing a strong contribution from multiply ionized ions. Hydrodynamic and collisional-radiative codes are used to extract the plasma temperature and density from these measurements. We show that our me...

Real-time optical measurements with picosecond resolution during laser induced transformations

This work describes a novel technique allowing to measure with picosecond resolution the time evolution of the optical properties ~reflectivity/transmission! of a material surface exposed to a single laser pulse. The experimental setup is based on the use of a streak camera in combination with a single-mode probe cw laser. The maximum achievable time resolution is about 1 ps for the acquisition...

Coherent ultrafast measurement of time-bin encoded photons.

Time-bin encoding is a robust form of optical quantum information, especially for transmission in optical fibers. To readout the information, the separation of the time bins must be larger than the detector time resolution, typically on the order of nanoseconds for photon counters. In the present work, we demonstrate a technique using a nonlinear interaction between chirped entangled time-bin p...
