WebMonodisperse citrate-stabilized gold nanoparticles with a uniform quasi-spherical shape of up to ∼200 nm and a narrow size distribution were synthesized following a kinetically controlled seeded growth strategy via the reduction of HAuCl4 by sodium citrate. The inhibition of any secondary nucleation during homogeneous growth was controlled by … WebIn ponderomotive self-focusing of a short laser pulse under plasma density ramp, the pulse acquires a minimum spot size. As the laser propagates through the density ramp region, it …
Three-Dimensional Manipulation for Self-Focusing Behavior
Webprofile of the intensity distribution [of the beam] can be so unsuited that it will cause aberration and beam separation.” Thus, self-focusing of a beam with a realistic beam profile, for example, Gaussian beam, shell be accompanied by aberration and distortion, i.e. the beam won’t focus to a point as predicted by the waveguide model [3]. WebSep 1, 2015 · This paper presents an investigation of the self-focusing of cosh-Gaussian laser beam in a plasma with linear absorption taking into account the combined effects of relativistic and ponderomotive… Expand 75 Relativistic and ponderomotive effects on evolution of laser beam in a non-uniform plasma channel T.
