Picosecond 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 کاملPicosecond laser-pump, x-ray probe spectroscopy of GaAs
A laser-pump, x-ray probe spectroscopic experiment is described, and the results are shown. The Ga Ka x-ray fluorescence following x-ray absorption, at the Ga K absorption edge was measured, and its increase due to excitation with subpicosecond pulses of laser light at 4.6 eV photon energy was determined. The x-ray absorption, and thus the fluorescence, is increased for about 200 ps after the l...
متن کاملPicosecond x-ray laser interferometry of dense plasmas.
We present the first results from picosecond interferometry of dense laser-produced plasmas using a soft x-ray laser. The picosecond duration and short wavelength of the 14.7 nm Ni-like Pd laser mitigates effects associated with motion blurring and refraction through millimeter-scale plasmas. This enables direct measurement of the electron-density profile to within 10 microm of the target surfa...
متن کاملPicosecond-resolution soft-x-ray laser plasma interferometry.
We describe a soft-x-ray laser interferometry technique that allows two-dimensional diagnosis of plasma electron density with picosecond time resolution. It consists of the combination of a robust high-throughput amplitude-division interferometer and a 14.7-nm transient-inversion soft-x-ray laser that produces approximately 5-ps pulses. Because of its picosecond resolution and short-wavelength ...
متن کاملX-ray Laser Research at Palaiseau
We present the soft X-ray laser experiments performed at Greco "Interaction Laser-Matisre" (Palaiseau). They are mainly concerned with Lithium-like ions of aluminum in plasmas produced by 1.06v Nd-laser. We describe the experimental set-up which performs time-dependent gain measurements. We report results showing a gain-length product of 2 2.5 for the 3d 5f line at 105.7 A . Comparison is made ...
