摘要:

By using optical Fourier‐transform techniques, we have obtained photgraphs of plasma density striations in the focal region of a 350‐MW CO2laser beam focused by anf/7.5 lens into a plasma with density 0.1nc. The observed spatial frequency and the estimated density change imply that the striated regions are also the regions of self‐trapped radiation channels.
