Probing the photophysical properties of fluorescent proteins using photoacoustic pump-probe spectroscopy and imaging [PDF]

Photoacoustics
Pump-probe excitation of fluorophores has been shown to overcome the limitations of conventional multiwavelength imaging and linear unmixing approaches by providing fluorophore-specific contrast whilst eliminating the dominant background signal of ...

Extracting quantitative dielectric properties from pump-probe spectroscopy [PDF]

Nature Communications, 2022
Photoinduced changes in transmission, reflection and scattering prevent conventional pump-probe spectroscopy to unambiguously assign the origin of spectral signatures. Ashoka et al.

Pump–probe capabilities at the SPB/SFX instrument of the European XFEL [PDF]

Journal of Synchrotron Radiation, 2022
Pump–probe experiments at X-ray free-electron laser (XFEL) facilities are a powerful tool for studying dynamics at ultrafast and longer timescales. Observing the dynamics in diverse scientific cases requires optical laser systems with a wide range of ...

A Non-Modulated Triaxial Magnetic Field Compensation Method for Spin-Exchange Relaxation-Free Magnetometer Based on Zero-Field Resonance

IEEE Access, 2019
In this study, we demonstrate a non-modulated triaxial magnetic field compensation method for spin-exchange relaxation-free (SERF) atomic magnetometers.

Evolution of dopant-induced helium nanoplasmas [PDF]

, 2012
Two-component nanoplasmas generated by strong-field ionization of doped helium nanodroplets are studied in a pump-probe experiment using few-cycle laser pulses in combination with molecular dynamics simulations.

Ultrafast spectroscopy of single molecules [PDF]

, 2007
We present a single-molecule study on femtosecond dynamics in multichromophoric systems, combining fs pump-probe, emission-spectra and fluorescence-lifetime analysis.

Holographic pump probe spectroscopy

Journal of High Energy Physics, 2018
We study the non-linear response of a 2+1 dimensional holographic model with weak momentum relaxation and finite charge density to an oscillatory electric field pump pulse.

Electrical control of inter-dot electron tunneling in a quantum dot molecule [PDF]

, 2012
We employ ultrafast pump-probe spectroscopy to directly monitor electron tunneling between discrete orbital states in a pair of spatially separated quantum dots.

Observation of Backward Guided-Acoustic-Wave Brillouin Scattering in Optical Fibers Using Pump–Probe Technique

IEEE Photonics Journal, 2016
We experimentally demonstrate the observation of backward (i.e., opposite of the direction of the pump) guided-acoustic-wave Brillouin scattering (GAWBS) using the pump–probe technique and investigate the spectral dependence on the pump– ...

Spatial-Dependent Hamiltonian Formulation of Cross-Mode Modulation

IEEE Photonics Journal, 2020
In the absence of random mode mixing (RMM), linearization of the cross-mode modulation (XMM) under pump-probe configuration is in general complicated because the evolution of the pump light depends on the local mode decomposition of itself. In this work,
