Picosecond 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 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-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 کاملDynamics of converging laser-created plasmas in semicylindrical cavities studied using soft x-ray laser interferometry.
The evolution of dense aluminum and carbon plasmas produced by laser irradiation of 500-microm -diam semicylindrical targets was studied using soft x-ray laser interferometry. Plasmas created heating the cavity walls with 120-ps -duration optical laser pulses of approximately 1x10;{12}Wcm;{-2} peak intensity were observed to expand and converge on axis to form a localized high-density plasma re...
متن کاملTwo-dimensional effects in laser-created plasmas measured with soft-x-ray laser interferometry.
Soft-x-ray laser interferograms of laser-created plasmas generated at moderate irradiation intensities (1 x 10(11)-7 x 10(12) W cm(-2)) with lambda=1.06 microm light pulses of approximately 13-ns-FWHM (full width at half maximum) duration and narrow focus (approximately 30 microm) reveal the unexpected formation of an inverted density profile with a density minimum on axis and distinct plasma s...
