With several kinds of cylinder cavity targets irradiated by 1.053 μm laser and using a spatial imaging technology, the spatial-resolution images of the jet of plasma at the laser entrance hole, inside of the cavity and X-ray transport channel are obtained. The spatial character of the jet of laser produced plasmas are observed.We also made observation on the jet of plasma using a planar target and a converting target of special geometry·A typical result in the experiment is given and discussed briefly.
