Paper Abstract

Investigated is the influence of isothermal annealing on the real structure and laser damage threshold of KDP single crystals. It is shown that the annealing of the samples at temperatures close to that of phase transition results in a pronounced decrease of the number of defects in the crystals, their optical homogeneity being improved. The chosen optical annealing conditions allow to raise the values of mechanical strength and laser damage threshold by 2 or 3 times and thereby to reduce the spread of these characteristics over the bulk of the crystals.
