Measurements of Brillouin-Backscatter Dependence on Density-Scale Lengths near Critical Density
The paper presents measurements of the Brillouin backscatter fraction made from laser produced spherical plasmas with prepared scale lengths of from 5 to 50 microns. It is shown that the scale lengths in the critical density region of 0.1 to 1 were measured using double-pulse holographic interferome...

| Summary: | The paper presents measurements of the Brillouin backscatter fraction made from laser produced spherical plasmas with prepared scale lengths of from 5 to 50 microns. It is shown that the scale lengths in the critical density region of 0.1 to 1 were measured using double-pulse holographic interferometry. The backscatter density was found to vary from 5% to 25% of the incident energy over the range of scale lengths measured. Finally, the spectra of the backscatter light were obtained and show the red shifts characteristic of Brillouin scattering. |
