The precise modeling of laser–target interactions in the regimes of tunneling ionization and barrier-suppression ionization is of significant importance, as these mechanisms dominate in the strong-field regime. In this study, we examine the dynamics of the transition from tunneling to barrier-suppression ionization by applying an empirically ...

Laser-induced breakdown in solids and gases involves complex ionization dynamics that occur on ultrafast time scales. In this work, we present a comparative review of the specific features of laser-induced breakdown (LIB) in gases and solid materials. We also present appropriate numerical approaches that allow the calculation of ionization event ra...

In this study, we explore the design, simulation, and deployment of a passive RC low-pass filter, specifically targeting its integration within Internet of Things (IoT) applications. We employed a symbolic computing environment to theoretically model the filter's frequency response, analytically deriving the transfer function and numerically valida...

In this study, we investigate the ultrafast dynamics of free electrons in skin-like tissue media, stimulated by laser pulses with durations between 50 fs and 100 fs. Our analysis is based on a rate-equation approach for the evolution of free electron density  under different laser pulse durations. The simulated electron densities are then used...

 This research focuses on the dynamics of electron behavior during the laserinduced breakdown (LIB) in skin tissues, pivotal for plasma generation in biomedical contexts. Through a numerical analysis centered on high-intensity Nd:YAG laser pulses within the 500–1000 nm wavelength range and a 10 ns pulse duration, we explore the balance ...
