Abstract
Thin films of Ge1-xSnxSe2 glasses were studied for self-developing hol ograms. The recording property of the films was found to depend on the tin fraction x. The peak values of the diffraction efficiency of reco rded holograms decrease as the tin content of the films increase. For films with x greater-than-or-equal-to 0.20 the recording property is n early nonexistent. The dependence of the peak diffraction efficiency o n the tin fraction x is correlated to that of photodarkening in these glasses.
