Experimental Test of Resonant Absorption Theory Progress Report: July-September 1979

The scaling of the hot electron temperature, T/sub h/, with laser intensity, I, has been studied with the laser-shockfront interaction apparatus. The preliminary result for 500 psec laser pulses of intensity I approx. 10/sup 14/ W/cm/sup 2/ is T/sub h/ infinity I/sup ..cap alpha../, where ..cap alpha.. = .35 to .40.

Experimental Test of Resonant Absorption Theory Progress Report: July-September 1978

Engineering of the various components of the experiment is discussed, and the first experiments are described. In the last three months engineering has been virtually completed on all aspects of this experiment, and the various components of the apparatus have been successfully integrated and utilized.

The laser-shockfront interaction experiment has been performed using the 100 psec FWHM pulses available from our newly installed high-pressure laser amplifier. The interaction time is so short that the hydrodynamic expansion which distinguishes H/sub 2/ targets from D/sub 2/ is absent. Good experimental reproducibility results.
