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

Studied were the strength characteristics of KDP crystals doped with l-arginine under a concentrated load and irradiation of the first harmonic YAG:Nd laser. The crystals were obtained by means of the temperature reduction method on a point seed, the content of l-arginine in the aqueous solution being 0.3, 0.
