Efficient pump-probe sampling with a single-cavity dual-comb laser: Application in ultrafast photoacoustics [PDF]
Ultrafast pump-probe measurements are used to characterize various samples, such as biological cells, bulk, and thin-film structures. However, typical implementations of the pump-probe apparatus are either slow or complex and costly hindering wide ...

Phase-matching free pulse retrieval based on plasma-induced defocusing [PDF]
A phase-matching free pulse retrieval technique based on plasma-induced defocusing in a rare gas is presented. Based on a pump-probe setup, this technique uses a moderately intense pump laser pulse for ionizing the medium, creating in turn an ultrafast ...

Phonon pump enhanced fast and slow light in a spinning optomechanical system
We investigate the properties of the optical output fields in a spinning optomechanical system under the condition of optomechanically induced transparency (OMIT), where the cavity is optically driven by a strong pump field and a weak probe field and the

Controllable Fast and Slow Light in Photonic-Molecule Optomechanics with Phonon Pump
We theoretically investigate the optical output fields of a photonic-molecule optomechanical system in an optomechanically induced transparency (OMIT) regime, in which the optomechanical cavity is optically driven by a strong pump laser field and a weak ...

Incoherent control of optical signals: Quantum-heat-engine approach
Optical pump-probe signals can be viewed as work done by the matter while transferring the energy between two coherent baths (from pump to probe). In thermodynamics, a heat engine, such as a laser, is a device which performs similar work but operating ...

Controlled ultrafast ππ*-πσ* dynamics in tryptophan-based peptides with tailored micro-environment
Pump-probe experiments in the gas phase usually target neutral molecules. Here the authors couple an electron spray source with ultrafast pump-probe UV-Vis spectroscopy, to follow the ππ*-πσ* coupling in tryptophan-based ions.

Pump-probe scheme for optical coherence tomography using indocyanine green mixed with albumin or human plasma [PDF]
Use of indocyanine green (ICG) in a pump-probe scheme for OCT is proposed. The study illustrates that ICG in protein solution shows unusual pump-probe imaging potential, indicating its usefulness as a contrast agent for ...
