The influence of various technological parameters of crystallization (acidity of growth solutions, crystallization temperature, growth rate, degree of solution purification) on the optical absorption of large KDP single crystals has been studied in the UV range of the spectrum. It is shown that the method of solvent recirculation with the use of the starting material with the microimpurity content not exceeding 5 × 10–5 wt % and solution ultrafiltration under the optimum crystallization conditions (tcr = 80°C, Vcr ∼ (0.8–1.6) × 10–6 cm/s, pH 4) enables one to grow KDP single crystals with cross sections up to 300 × 300 mm2 and the transmission in the vicinity of the fundamental absorption edge (λ = 200 nm) equal to 86%. © 2004 MAIK “Nauka / Interperiodica”.
