Abstract
Hydrodynamic Time Scale of Resonance in Intense Laser Irradiated Nano-Plasmaof Different Geometries
Highlights
Absorption of intense laser pulses in plasmas is a widely pursued challenging problem [1]
It is not a surprise that a wide number of studies have been devoted to finding targets like nanostructures of various shape, size, morphology and geometry for efficient laser energy coupling [13].For this purpose solid nanostructures like spherical gas clusters [14], metal clusters [15], nano-rods [16], nano-tubes [17], nano-shells etc. are used
In this work we analytically predict the hydrodynamic time scales for occurrence of resonance in various nanostructures of different geometries
Summary
Absorption of intense laser pulses in plasmas is a widely pursued challenging problem [1]. Little study has been done previously to analytically predict the time scales / laser pulse duration and intensity required for exciting resonance in nanostructures of different shapes and geometries. In this work we analytically predict the hydrodynamic time scales for occurrence of resonance in various nanostructures of different geometries In addition to this the role of laser intensity in accelerating the density. These results in the nano-rod shape modification to become nanoelliptical causing an increase of its resonance density. These graphs convey very the time scales of resonance in various nano-particles of different size and interacting at different laser intensities.
