Generation of strongly coupled plasmas by high power excimer laser
High power excimer laser is a kind of excellent energy source due to smooth power profile and short wavelength (ultraviolet).To generate strongly coupled plasmas (SCP) by high power excimer laser, an Au-CH-A1-CH target is used to make the A1 sample reach the state of SCP, in which the Au layer transforms laser energy to X-my that heating the sample by volume and the CH layers provides necessary constraints.With aid of the MULTI-1D code, we calculate the state of the A1 sample and its relationship with peak intensity, width and wavelength of laser pulses.The calculated results suggest that an excimer laser with peak intensity of the magnitude of 1013W/cm2 and pulse width being 5ns-10ns is suitable to generate SCP with the temperature being tens of eV and the density of electron being of the order of 1022/cm-3.Lasers with shorter wavelength, such as KrF laser, are preferable.
