X-Ray Generation by High Irradiance Exawatt-Per-Square Centimeter Subpicosecond Lasers,
Abstract
We have studied the interaction of 290-fsec, 308-nm laser pulses with Aluminum targets at irradiances exceeding ((5 x 10 to the 18th W)/sq. cm.) (5 EW/sq. cm). The x-ray spectrum shows a hot electron component with a characteristic temperature of 30 keV, and a low temperature component of 1 keV. Imaging of the x-rays shows an emission region of few micrometers for the hot component and a larger region for the 1 keV emission. The x-ray brightest lines radiating 0.6% of the incident laser light energy. The spectral luminosity of the L sub alpha line was measured to be (3 x 10 to the 14th W)/sq. cm./eV/sr.
