248 Recent Achievements in Plasma Harmonics
from many targets. So, here we were able to improve the stability
of harmonics (and correspondingly stability of plasma formation
conditions) not just by using the fresh (non-ablated) surface but by
changing the conditions of overheating of the same spot of the target.
On the basis of our experiments with different (rotating and fixed)
targets, we concluded that the overheating of the same spot worsens
the conditions for stable plasma formation. The morphology of the
heating spot did not remain intact during these experiments. At
the same time, ...
