High resolution hard x-ray spectroscopy of femtosecond laser-produced plasmas with a CZT detector
We present measurement of characteristic Ka emission from Mo, Ag, and La targets irradiated by a 60 fs, 600 mJ, 10 Hz Ti:sapphire laser pulse at 10– 10 W/cm. These x-ray emissions can potentially be used in applications from laser-based hard x-ray sources to x-ray mammography so detailed knowledge of the spectra is required to assess imaging of the figure of merit. We show here that high resolv...
متن کاملInvestigation laser-produced chlorine plasmas for x-ray scattering experiments
For future investigations of strongly coupled plasmas with electron temperature above the Fermi temperature, Ne near solid density and the electron-electron coupling paramter Γee > 1, there is a need for new diagnostics. This matter has such a low temperature, that emission spectroscopy is not possible and probing with visible or UV-light is also impossible as it cannot penetrate the plasma due...
متن کاملX-Ray Crystal Spectroscopy of Sub-picosecond Laser-Produced Plasmas beyond 50 keV.
The interaction of a sub-picosecond (sub-ps) laser with a high-Z target produces a hard x-ray continuum, but to our knowledge no high-resolution study of the line emission is known. We present here crystal spectroscopy as a tool for the observation of energetic line x-radiation from a sub-ps laser-produced plasma. Reflection properties of flat and bent crystals for x-ray spectroscopy are analyz...
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 کاملX-ray polarization spectroscopy to study energy transport in ultra-high intensity laser produced plasmas
X-ray polarization spectroscopy was studied to derive directly the velocity distribution function (VDF) of hot electrons propagating in plasma created with a high intensity laser pulse. Polarization measurement was made at around 10 W/cm using a laser pulse (~10 J in ~1 ps) from Alisé facility at CEA/CESTA. Chlorinated triple-layer targets were irradiated, and Cl He line was observed with an x-...
