Backscatter measurements from laser-produced plasmas at 10.6 μm

Abstract
The fraction of light backscattered from plasmas produced by 10.6‐μm laser light focused on polyethylene slab targets is ∼5% of the incident for intensities between 1013 and 1015 W/cm2. Time‐integrated measurements of the spectrum of backscattered light near 10.6 μm are presented.
