Abstract:

The problem of reconstructing the laser beam intensity distribution from temperature distribution over the front surface of the target heated by the beam has been solved analytically. The dynamic relations have been derived for the instantaneous position of the intensity distribution centroid, size, and the functional of focusing with arbitrary boundary conditions on the back surface of the target.
