FIELD: physics, optics.
SUBSTANCE: invention is related to the field of optical equipment. In monoblock arrester body comprises internal cavity filled with limiting substance that possesses non-linear absorption. Limiting substance used may be flaking solution with lower critical point, in particular water solution of triethylamine with concentration of Cwork.=(32±2) wt %, at working temperature of solution that is less than critical temperature (twork.<tcrit.=18.163°C) or water solution of 2-butoxyethanol with concentration of Cwork=(30±2) wt %, when working temperature of solution is less than its critical temperature (twork.<tcrit.=48.272°C).
EFFECT: creation of laser radiation arrester with high initial transmission and wide range of waves working lengths that provides for neutral coloring of optical instruments field of view.
