2010 10th International Conference on Laser and Fiber-Optical Networks Modeling.
Electrical dc conductivity and laser damage threshold of pure and urea doped KH 2 PO 4 crystals are investigated. It is found that the crystals with a low electrical conductivity have a high laser damage threshold. It is shown that increase of the re

Under the effect of ionizing radiation on KDP and DKDP crystals radiation-stimulated defects are formed in them. It was found that crystals with a higher content of cationic impurities are noticeably strengthened under the effect of electron radiatio
