An. Kuzmin et al., UTILIZATION OF IR LASER-PUMPED ANTI-STOKES EMISSION OF ER-YB DOPED SYSTEMS FOR IDENTIFICATION OF SECURITIES, Acta Physica Polonica. A, 90(2), 1996, pp. 423-426
In this paper we present a utilization of anti-Stokes luminescence of
Er-Yb systems for identifications of securities. A simple method of de
tection of an up-conversion phenomenon in such system by means of IR l
aser operating in the region 960-1010 nm is proposed.
