We present a laboratory system for single-shot magneto-optical (MO) imaging of ultrafast magnetization dynamics with less than 8 fs temporal, micrometer spatial resolutions and a MO Faraday's rotation sensitivity of 4 mdeg/μm. We create a stack of MO images repeatedly employing a single pair of pump and defocused probe pulses to induce and visualize MO changes in the sample. Both laser beams are independently wavelength-tunable, allowing for a flexible, resonant adjustable two-color pump and…

Ultrafast time-resolved magneto-optical imaging of all-optical switching in GdFeCo with femtosecond time-resolution and a μm spatial-resolution.
An ultrafast time-resolved magneto-optical (MO) imaging system with several millidegree resolution of light polarization angle, 100 fs time-resolution, and a micrometer spatial resolution is developed, which significantly improves the speed for MO imaging.
Single-shot ultrafast optical imaging.
This mini-review surveys comprehensively the state-of-the-art single-shot ultrafast optical imaging and describes operating principles, present representative cutting-edge techniques with a particular emphasis on their methodology and applications, and discusses their advantages and challenges.
Dual-shot dynamics and ultimate frequency of all-optical magnetic recording on GdFeCo
Researchers led by Xiangping Li and Alexey Kimel have experimentally determined the fastest possible rate of the optical reversal of magnetization achieved by this promising new technology and suggest data switching repetition rates of up to three billion cycles per second (3 GHz) are feasible.
High-sensitive scanning laser magneto-optical imaging system.
The developed MO system enables the fast and quantitative imaging of a rotationally symmetric magnetic field distribution around an YBa(2)Cu(3)O(7-delta) (YBCO) strip line applied with dc-biased current and the detection of quantized fine signals corresponding to magnetic flux quantum generation in a superconducting loop of an YBCO Josephson vortex flow transistor.

Ultrafast path for optical magnetization reversal via a strongly nonequilibrium state.
Using time-resolved single-shot pump-probe microscopy the mechanism and the time scale of all-optical magnetization reversal by a single circularly polarized 100 fs laser pulse are unveiled and it is demonstrated that for a 5 microm domain the magnetic information can be recorded and readout within 30 ps, which is the fastest "write-read" event demonstrated for magnetic recording so far.

and thus has a linear character. We demonstrate that this all-optically driven linear reversal can be modeled as a result of a two-fold impact of the laser pulse on the medium. First, due to
Ultrafast non-thermal control of magnetization by instantaneous photomagnetic pulses
It is demonstrated that circularly polarized femtosecond laser pulses can be used to non-thermally excite and coherently control the spin dynamics in magnets by way of the inverse Faraday effect, and offers prospects for applications of ultrafast lasers in magnetic devices.

A table-top setup to perform magneto-optical pump-probe measurements with the possibility to independently tune the photon-energy of both pump and probe beams in the 0.5 eV-3.5eV range is developed and proved by measuring the ultrafast demagnetization of a cobalt crystal as a function of a wide variety of experimental parameters.
Femtosecond single-shot imaging of nanoscale ferromagnetic order in Co/Pd multilayers using resonant x-ray holography.
