ChemCatChem, Volume 18, Issue 7, 14 April 2026.ABSTRACT Pulsed laser excitation offers a compelling approach for accessing nonequilibrium conditions in catalysis by delivering energy to surfaces in a highly localized and time‐controlled manner. In contrast to continuous‐wave irradiation, pulsed lasers concentrate energy into extremely short bursts—ranging from femtoseconds to nanoseconds—which can ...

Diffusion of photoexcited carriers in graphene
, 2012 The diffusion of electron-hole pairs, which are excited in an intrinsic graphene by the ultrashort focused laser pulse in mid-IR or visible spectral region, is described for the cases of peak-like or spread over the passive region distributions of ...

Free‐Space Time‐Bin Encoded Quantum Key Distribution from Near‐ to Mid‐Infrared Wavelengths
Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.This work investigates free‐space communication based on quantum key distribution (QKD) in the mid‐infrared. Time‐bin encoded QKD is simulated, and it is demonstrated that a free‐space QKD link operating in the mid‐infrared outperforms configurations based on conventional near‐infrared wavelengths under various weather scenarios, with a particular ...

High order optical sideband generation with Terahertz quantum cascade lasers [PDF]
, 2013 Optical sidebands are generated by difference frequency mixing between a resonant bandgap near-infrared beam and a terahertz (THz) wave. This is realized within the cavity of a THz quantum cascade laser using resonantly enhanced non-linearities. Multiple

Double Helical Plasmonic Antennas
Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Towards unstrained interband cascade lasers
Applied Physics Express, 2017 We propose designs for the active region of an interband cascade laser by utilizing a combination of In(As,Sb) and (Ga,In)(As,Sb) materials in a type-II system for strain control and to eventually make the entire quantum well lattice-matched to GaSb or InAs substrates.
