14 November 2001 High-resolution spectroscopy of a subpicosecond laser-produced lanthanum plasma

Hot dense lanthanum plasmas have been produced by irradiating a solid Lanthanum target with a high contrast 400fs laser pulses at 3 X 1018 W/cm2. The M-shell emission has been recorded in the wavelength range 10A-14A using a high-resolution crystal spectrometer. The emission has been time resolved using our PX1 x-ray streak camera with a temporal resolution of 350fs. A superconfiguration model for non-LTE plasmas coupled to hydrodynamics calculations is used to discuss the measurements. Our work indicates that a correct understanding of intermediate and high Z dense plasmas, created with femtosecond clean laser pluses, requires time resolved spectroscopy with femtosecond resolution and NLTE atomic physics coupled to plasma hydrodynamics.
