Laser‐driven hydrodynamic perturbation in an overdense Z‐pinch plasma
(The American Institute of Physics, 1979-04)
Holographic interferometry of the interaction of a radially incident intense CO2 laser beam (1011 W/cm2, 38‐nsec FWHM pulse) with an overdense helium Z‐pinch plasma (ne≳1019 e/cm3, Te∼20 eV, L=100 μm) has indicated the ...
Interferometric characterization of density dynamics of an ultradense Z‐pinch plasma
(The American Institute of Physics, 1979-04)
We have measured the spatially and temporally resolved density in a Z‐pinch plasma by holographic interferometry. The high electron density (4×1019 e/cm3), short density scale length (100 μm), and low temperature (about ...
Optical alignment procedure for an unstable resonator high‐power laser
(The American Institute of Physics, 1977-12)
A method for aligning the optics of a pulsed high‐power positive branch unstable resonator is described. The procedure relies on the distribution of the output beam and is thus independent of a separate alignment laser, ...
Intensity dependence of transmission of electromagnetic radiation through an overdense Z‐pinch plasma
(The American Institute of Physics, 1979-03-15)
The interaction of a 10.6‐μm‐wavelength electromagnetic wave with an independently created overdense plasma has been investigated at incident intensities on either side of the field‐strength condition Vosc/Vth=1. An intensity ...
Characterization of an ultradense reproducible Z pinch
(The American Institute of Physics, 1977-12-15)
The apparent complexity of the laser‐plasma coupling in laser fusion target irradiation has stimulated the need for carefully controlled experimental studies of the laser‐plasma interaction at the critical surface. A helium ...
