Anharmonic resonance absorption of short laser pulses in clusters: A molecular dynamics simulation study

Anharmonic resonance absorption of short laser pulses in clusters: A molecular dynamics simulation study

Linear resonance (LR) absorption of an intense 800~nm laser light in a nano-cluster requires a long laser pulse > 100~fs when Mie-plasma frequency ($\omegaMie$) of electrons in the expanding cluster matches the laser frequency~($\omega$). For a short duration of the pulse the condition for LR is not satisfied. In this …
