Micrometer-thin liquid sheets from single-jet impact on a sharp edge for multi-kHz laser-plasma experiments
Mukesh Kumar, S. Sree Harsha, Prashant Kumar Singh
We present a simple and robust method for generating freely suspended liquid sheets by directing a single laminar liquid jet onto the sharp edge of an inclined plate. By optimizing…

Femtosecond laser-induced cavitation seeds liquid-jet breakup beyond the Rayleigh-Plateau stability limit
Sourabh Singh, Tamanna, S. Sree Harsha +1
The Rayleigh-Plateau instability predicts that infinitesimal perturbations of a liquid jet grow only for kR < 1, with kR = 1 marking the classical stability boundary. Here, we show…

Caustic-Driven Fluidic Microlenses for Enhanced Nonlinear and High-Energy-Density Physics
Sourabh Singh, S. Sree Harsha, Tamanna +1
We demonstrate that caustic microlensing occurring in a liquid jet efficiently drives linear, nonlinear, and high-energy-density phenomena. In the linear regime, caustics provide l…
