Description
By using optical Fourier-transform techniques, we have obtained photgraphs of plasma density striations in the focal region of a 350-MW CO2 laser beam focused by an f/7.5 lens into a plasma with density 0.1n/sub c/ . The observed spatial frequency and the estimated density change imply that the striated regions are also the regions of self-trapped radiation channels
