Single-shot compressed ultrafast photography: a review [PDF]

, 2020
Compressed ultrafast photography (CUP) is a burgeoning single-shot computational imaging technique that provides an imaging speed as high as 10 trillion frames per second and a sequence depth of up to a few hundred frames.

Ultrafast dynamics microscopy

Applied Physics Letters, 2000
We report the three-dimensional imaging of the vibrational, solvent, orientational, and electronic relaxation in organic fluorescent samples at 200–500 nm spatial resolution. This is achieved in steady-state recordings by exciting the fluorophore with a femtosecond pulse and subsequent quenching with a time-delayed, redshifted femtosecond pulse through

Impact and Recovery Process of Mini Flash Crashes: An Empirical Study

, 2017
In an Ultrafast Extreme Event (or Mini Flash Crash), the price of a traded stock increases or decreases strongly within milliseconds. We present a detailed study of Ultrafast Extreme Events in stock market data.

Dual-beam multipass cell compression for time-resolved femtosecond spectroscopy setups [PDF]

EPJ Web of Conferences
We present a dual-beam single multi-pass cell compressor designed for applications in time-resolved pump-probe spectroscopy. A single MPC simultaneously compresses two beams with different pulse energies to the same pulse duration, allowing for ...

2.76–3.98 μm picosecond mid-infrared optical parametric generation in a muti-grating MgO: PPLN

Frontiers in Physics, 2022
The high repetition rate, widely tunable, picosecond mid-infrared laser plays an important role in various fields. In this paper, the single-pass optical parametric generator (OPG) pumped by Yb-fiber laser based on MgO: PPLN is proposed.

Numerical method for nonlinear optical spectroscopies: Ultrafast ultrafast spectroscopy [PDF]

The Journal of Chemical Physics, 2019
We outline a novel numerical method, called Ultrafast Ultrafast (UF2) spectroscopy, for calculating the nth-order wavepackets required for calculating n-wave mixing signals. The method is simple to implement, and we demonstrate that it is computationally more efficient than other methods in a wide range of use cases. The resulting spectra are identical
