Correlation of defect centers with photoinduced second-harmonic generation in Er- and Sm-doped aluminosilicate fibers.
The spectral dependence of photoinduced optical losses after chi((2)) writing have been obtained in Sm- and Er-doped fibers. The results show that Sm(2+) and Er(2+) can be a source of photoelectrons during fiber preparation.
