Tóm tắt

The propagation of laser ablation plumes from 248 nm laser-irradiated YBCO into vacuum and 100 mTorr ambient oxygen has been photographed with a gated, intensified CCD array camera system. The thermalization of the laser plasma and onset of shock structures due to collisions with the background gas are investigated from two-dimensional digitized images of the visible plume emission.
