KDP crystals as an optical element in high-power laser system

This research presents a study of the dependence of the addition of ethylenediaminetetraacetic acid to the KDP crystal on the crystal growth kinetics and its physical-optical properties: width of the dead zone, growth rate of crystal faces, and transmission spectra. Obtained data on the change of dead zone width of growth solutions with concentrations of 0, 0.001, 0.005, 0.015, 0.02 mol% EDTA. KDP crystal was grown by the method of high-speed growth of oriented crystals, its transmission spectra in the range from 200 to 1100 nm were obtained. The possibility of adding EDTA when growing KDP crystals by the high-speed method is discussed.
