In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air

open access: yesLaser &Photonics Reviews, EarlyView.
Air‐breakdown acoustics at the laser focus is used to determine femtosecond pulse duration with a simple USB microphone. By chirp‐tuning and compressing 1030 nm pulses from 241 to 50 fs, the acoustic amplitude scales inversely proportional to the square root of the pulse duration, enabling in situ readout over 50 fs–5 ps—crucial for precise pulse ...

Engineering Nanoemulsions to Maximize NIR‐II Fluorescence and Preserve Photothermal Performance of a Novel Boron Difluoride Formazanate Dye

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
An oil‐in‐water nanoemulsion transforms a boron difluoride formazanate (BDF) dye into a dual‐modal imaging‐guided theranostic agent (BDF‐NE). Its nonpolar oil core maximizes NIR‐II fluorescence while maintaining strong photoacoustic contrast to guide photothermal therapy with high photostability and 66.8% photothermal conversion efficiency, achieving ...
