title: Self induced gratings in ternary SiO2:SnO2:Na2O bulk glasses by UV light seeding.
abstract: The diffraction efficiency of gratings written in ternary SnO2:SiO2:Na2O bulk glasses rises dramatically with time after the occultation of the cw 244nm light used to write the thick hologram. This self-induced behavior lasts for several hours and ultimately leads to refractive index changes as high as 3 10-3.
