Brilliance Improvement of a Laser-Produced Soft X-Ray Plasma
The brilliance of a laser-produced soft X-ray source is enhanced for gaseous target concepts. In contrast to solid or liquid target materials, these sources are clean and versatile but provide a comparably low conversion efficiency of laser energy into EUV and soft X-ray radiation. The basic idea is to induce supersonic effects in the gas jet, leading to a local increase of the particle density...
متن کاملDevelopment of a time-resolved soft x-ray spectrometer for laser produced plasma experiments.
A 2400 lines/mm variable-spaced grating spectrometer has been used to measure soft x-ray emission (8-22 Å) from laser-produced plasma experiments at Lawrence Livermore National Laboratory's Compact Multipulse Terrawatt (COMET) Laser Facility. The spectrometer was coupled to a Kentech x-ray streak camera to study the temporal evolution of soft x rays emitted from the back of the Mylar and the co...
متن کاملCharge recombination in soft x-ray laser produced nanoplasmas
The ionization and charge separation processes of nanoplasmas created by resonant excitation of atomic clusters in intense soft x-ray pulses have been investigated. Through irradiation with femtosecond pulses from the FLASH free electron laser (FEL) at λ = 13.7 nm and power densities exceeding 1014 W cm−2 the clusters are highly ionized with transient atomic charge states up to 9+. Variation of...
متن کاملPicosecond soft x ray source from subpicosecond laser produced plasmas
Short pulse high intensity laser plasma interactions are investigated experimentally with temporally and spectrally resolved soft x ray diagnostics We demonstrate that the pulse width of the laser produced x rays emitted from solid targets may be varied down to the picosecond time scale by adjusting the incident laser ux Bright picosecond broadband emission characteristic of a short scale lengt...
متن کاملSpace- and time-resolved soft x-ray emission from laser-produced magnesium plasma
Soft x-ray emission from plasmas produced by ablation from a magnesium target employing a ruby laser is studied using a grazing incidence spectrograph in the spectral region 3–12 nm. Emission intensities are investigated for different ionic lines as a function of position, time after the maximum of the laser pulse and laser irradiance. A gated pinhole camera is employed for studying the evoluti...
