Abstract
Low‐ and high‐atomic‐number targets were irradiated at normal and oblique incidences with high focused intensity, 2.5‐nsec duration of 1.06‐μm laser pulses. Calorimetry and spectroscopy of ω and 2ω light reflected back into the focusing lens was performed. Results show a dramatic reduction in the specularly reflected light from high‐atomic‐number targets. Brillouin backscatter was observed throughout the range 1014–1016 W/cm2. 2ω spectra indicated the presence of an electron‐ion decay instability with a threshold at 2×1015 W/cm2.Keywords
