摘要：

Experimental evidence for filamentation of CO2-laser radiation in an underdense, hydrogen plasma has been obtained from temporally resolved x-ray measurements. Transient x-ray bursts due to high-energy electrons in a filament of size ∼2λ are observed superimposed upon the cold thermal bremsstrahlung emission. A strong correlation between the high-energy x-ray emission and stimulated Brillouin scattering has also been observed, both in saturation characteristic and spatial dimensions. © 1979 The American Physical Society.
