The dislocation density in KDP crystals has been determined by X‐ray diffraction topography (L ANG method). A method for determining the laser damage thresholds in dependence on dislocation density is described. It is found that dislocations with a density about 10 3 cm −2 reduce the laser damage threshold up to a factor of two compared with perfect regions. It is shown that experimentally measured damage results can be explained theoretically.
