Abstract
Laser plasma has been produced within the surmac with geometric mirrors, by focussing the output beam of TEA CO2 laser (10.6 μm, 1 J) on the cross-linked polyethylen target. The production process of laser plasma has been observed by image converter camera. The result indicates that two groups of laser-produced plasma are formed during the production process. In the experiments of laser plasma confinement by surmac, maximum plasma potential of +20 V is formed with time. The potential difference between different points spatially is produced at the same time and it gradually becomes the value of the ambipolar potential.
