Short-pulse laser-produced plasmas
In this review, the physics of short-pulse laser-produced plasmas at moderate intensities is described, together with applications to x-ray sources and material processing.
متن کاملDiagnostics of laser-produced plasmas
Laser-produced plasmas are used for a variety of studies, relevant for both basic physics and applications, and are of course essential within the study of inertial confi nement approach to nuclear fusion. Because of this large interest, a large variety of diagnostics have been developed and are routinely used to unveil the physical processes at work during plasma process and laser-plasma inter...
متن کاملSpace Resolved Study of Laser Produced Plasmas
The study of plasma accelerated ions is an important topic nowadays [1]. The acceleration of ions is produced for electric fields caused by plasma density gradients. So a diagnostic of the plasma density and temperature is necessary. It is frequently achieved using spectroscopic methods with the light from He-like and Li-like plasma ion transitions emitted in the soft x-ray region, 1-1000 Å wav...
متن کاملFast - Discharge - Initiated KrF Laser
Intense laser emission has been observed from the KrF molecule formed by a chemical reaction initiated by fast-discharge circuitry. With a gas mixture of He:Kr:NF, = 500:50:1 and a sample pressure of 700 Torr, an output energy of 0. 8 mj was measured from a 25-nsec laser pulse (FWHM). Spectral analysis of the laser emission indicated laser action at 248.5 and 249.5 nm.
متن کاملMev X rays and photoneutrons from femtosecond laser-produced plasmas.
We demonstrate a novel method to monitor the total angular distribution of the spectrum of hard x-ray emission from a plasma generated with femtosecond laser pulses with an intensity of 5 x 10(18) W/cm2 on a solid target. Measured and calculated angular distributions of x rays show a pronounced anisotropy for MeV photon energies. We complemented the spectral information by demonstrating a (gamm...
