Effect of L-arginine on the optical properties, crystalline perfection and laser damage threshold of KDP crystals

Effect of doping of KDP crystal with amino acid l-arginine on the strength properties and character of laser damage

“…The observed decrease of microhardness values of KDP crystals doped with l -arg in comparison with those of pure KDP seems to be bound up with weakening of the interatomic bonds in the crystal lattice due to incorporation of 1.4 wt% of l -arg. As shown in [10] , [11] , l -arg molecules enter into the prismatic and pyramidal growth sectors of KDP crystal that is caused by the ability of the amino acid molecules to form hydrogen bonds with the growing crystal face {1 0 0}, and to interact electro statically with the positively charged face {1 0 1}. Presented in Fig.…”

“…The samples to be investigated were obtained from both growth sectors. We have previously shown that the doping in the range of 0.3–1.4 wt% concentrations lead to an increase of the efficiency of second harmonic generation by 1.33–2.53 times in the pyramidal sector, and in the 2.36–3.95 times in prismatic sector [10] , [11] .
