Diffraction-limited low power laser beams at 1.06 and 3.8 microm were focused by a 91-cm diam aperture onto a receiver located 10.5 km away on a low slant angle path over a desert basin. The analysis of beam areas and turbulence levels was used to determine a new scaling law for tilt-corrected turbulence-induced beam spread.

Xenon gas has been compressively heated from 8000 K to 15 000 K at peak pressures of 800-2400 atm. Brightness measurements were made of the emitted radiation at selected wavelengths in the visible. In a few cases, a time-resolved spectrum was obtained. The results obtained from a theoretical analysis are shown to be in reasonable agreement with experimentally measured values. A high efficiency for conversion of mechanical energy to radiant energy is indicated and suggests the use of such a device as an efficient source for laser pumping.
