摘要:

Underdense foam targets were irradiated with a single UV laser beam at intensities up to 1015W/cm2. The incident laser propagated into the foam a distance of 500–1000 &mgr;m, depending on the average target density. The backscattered Brillouin and 3&ohgr;0/2 radiation were observed to have the same dependence on the incident laser intensity, indicating a strong interrelation of these processes. A possible coupling mechanism is proposed.
