The propagation of the superthermal plasma from microdisk targets irradiated with single, nanosecond CO/sub 2/ laser pulses at intensities of approx.10/sup 14/ W cm/sup -2/ is examined through the study of its effect on subsidiary passive targets. The observed propagation velocity is similar to the estimated superthermal ion acoustic speed and has an intensity dependence of I/sup 0.14-0.21/.
