We have characterized the plasma produced by a picosecond laser pulse using x-ray spectroscopy. High-resolution high-sensitivity spectra of K -shell emission from a Ti plasma have been obtained, showing a strong contribution from multiply ionized ions. Hydrodynamic and collisional-radiative codes are used to extract the plasma temperature and density from these measurements. We show that our me...

Laser-produced plasma is a promising compact light source applicable in broad range of wavelengths. We performed spectroscopic analysis and characterization the laser-produced Al, Fe, Cu, Inconel alloy (Ni/Cr/Fe) to explore their potential applications far-ultraviolet (FUV) region where these methods are yet widely exploited. The emission spectrum from each target exhibited characteristic spect...

When high energy infrared laser pulses are incident on fused silica, the surface of silica is damaged and a laser-induced plasma produced. Based theory fluid mechanics gas dynamics, two-dimensional axisymmetric dynamic model was established to simulate generation process induced by millisecond pulse laser. The results show that temperature central region irradiated highest, first produced in th...

LLE Review, Volume 84 173 Introduction A key issue for inertial confinement fusion (ICF)1–3 is the Rayleigh–Taylor (RT) hydrodynamic instability.4,5 In directdrive ICF, nonuniformities in the drive laser produce pressure variations that “imprint” perturbations into the target. Unstable RT growth can amplify these perturbations, resulting in sufficient distortion of the target shell to degrade i...
