Controlling the construction of physical colors on the surfaces of transparent dielectric crystals is crucial for surface coloration and anti-counterfeiting applications. In this study, we present a novel approach to cre...

ABSTRACTSome parameters and their effects on CO2 laser output were studied in this research. This has been done through studying the effect of gases mixture pressure inside the electrical discharge tube and effect of ele...

"We show that, under certain conditions, modulation instability in nonlinear waveguides gives rise to the usual double-sideband spectral structure, but with a Raman gain profile. This process is enabled by the energy tra...

Stark widths and shifts of Nb II spectral lines have been measured by laser-induced breakdown spectroscopy (LIBS). The experimental line profiles are obtained from spectra of the emission of laser-induced plasmas generat...

An optical vortex possesses a ring-shaped spatial profile and orbital angular momentum (OAM) owing to its helical wavefront. This form of structured light has garnered significant attention in recent years, and it has e...

MXene as a novel two-dimensional (2D) material exhibits a lot of advantages in nonlinear optics. However, the common MXene, Ti3C2Tx and Ti2CTx nanosheets, easily suffer from degradation under ambient conditions, greatly ...

One of the main figures of merit in laser-ablative propulsion is the specific impulse, Isp, defined as the impulse per unit weight of fuel, and it is related to the exhaust velocity, ve, by the acceleration of gravity, I...

Abstract Background The objective of this in vitro study was to assess the anti-biofilm efficacy of super-oxidized water and ozonated water, activated through various methods, against Enterococcus faecalis (E. faecalis) ...
