104 MHz rate single-shot recording with subpicosecond resolution using temporal imaging.
We demonstrate temporal imaging for the measurement and characterization of optical arbitrary waveforms and events. The system measures single-shot 200 ps frames at a rate of 104 MHz, where each frame is time magnified by a factor of -42.4x. Impulse response tests show that the system enables 783 fs resolution when placed at the front end of a 20 GHz oscilloscope. Modulated pulse trains charact...
متن کاملSingle Shot Longitudinal Bunch Profile Measurements at Flash Using Electro-optic Techniques
For the high-gain operation of a SASE FEL, extremely short electron bunches are essential to generate sufficiently high peak currents. At the superconducting linac of FLASH at DESY, we have installed an electro-optic experiment with temporal decoding and spectral decoding to probe the time structure of the electric field of single sub-200 fs electron bunches. In this technique, the fieldinduced...
متن کاملElectro-optic technique with improved time resolution for real-time, nondestructive, single-shot measurements of femtosecond electron bunch profiles.
Electro-optic detection of the Coulomb field of a relativistic electron bunch combined with single-shot cross correlation of optical pulses is used to enable single-shot measurements of the shape and length of femtosecond electron bunches. This method overcomes a fundamental time-resolution limit of previous single-shot electro-optic measurements, which arises from the inseparability of time an...
متن کاملSingle-shot Longitudinal Bunch Profile Measurements at Flash Using Electro-optic Detection: Experiment, Simulation, and Validation
At the superconducting linac of FLASH at DESY, we have installed an electro-optic (EO) experiment for singleshot, non-destructive measurements of the longitudinal electric charge distribution of individual electron bunches. The time profile of the electric bunch field is electrooptically encoded onto a chirped titanium-sapphire laser pulse. In the decoding step, the profile is retrieved either ...
متن کاملA compact streak camera for 150 fs time resolved measurement of bright pulses in ultrafast electron diffraction.
We have developed a compact streak camera suitable for measuring the duration of highly charged subrelativistic femtosecond electron bunches with an energy bandwidth in the order of 0.1%, as frequently used in ultrafast electron diffraction (UED) experiments for the investigation of ultrafast structural dynamics. The device operates in accumulation mode with 50 fs shot-to-shot timing jitter, an...
