Picosecond soft x ray source from subpicosecond laser produced plasmas
نویسندگان
چکیده
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 length high density plasma is produced only when a high laser contrast is used The results are found to be in qualitative agreement with both the predictions of a simple model of radiation from a collisionally dominated atomic system and the results from a numerical simulation

Intense picosecond X-Ray pulses from laser plasmas by use of nanostructured "Velvet" targets
We describe the optical, radiative, and laser-plasma physics of a new type of nanostructured surface especially promising as a very high absorption target for high-peak-power subpicosecond laser-matter interaction. This oriented-nanowire material, irradiated by 1 ps pulses at intensities up to 10(17) W cm(-2), produces picosecond soft x-ray pulses 50x more efficiently than do solid targets. We ...
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 کاملLaser-produced MeV electrons and hard X-ray spectroscopic diagnostics
A new spectroscopic technique for the measurement of the sizes of hard X-ray sources produced by the irradiation of solid-density targets by intense laser radiation is discussed. The technique is based on the source broadening of K shell spectral lines from targets irradiated by intense picosecond laser pulses. The spectra are recorded by a modified Cauchois type spectrometer, where the detecto...
