HeNe laser radiation was studied in aqueous solutions of alkali hydroxides and salts with the following anions: F-, Cl-, Br-, I-, CO:-and SO:-. The etching rate depends on the size of the ions in solution. The isomorphic properties of some NH:, Rb+ and K+ salts were also investigated with respect to
