A theoretical study of a laserhyphen;irradiated capillary discharge

摘要

A theoretical study of a laserhyphen;irradiated capillary discharge is presented. The discharge produces a columnar flow of lowhyphen;temperature plasma (1 eV) with a density of 1019atoms/cm3. This ambient lowhyphen;temperature plasma is then irradiated by a 1.06hyphen;mgr;m Nd glass laser with pulse lengths from 100 ps to 1 ns. The resultant plasma is studied, using hydrodynamic simulations coupled to a detailed kinetics model.
