Abstract :
Summary form only given. Photorefractivity of sol gel prepared silica films were confirmed from two-beam-coupling measurements, performed with a He-Ne cw laser at 633 nm without applied electric field. A strong absorption was present, however the relative energy transfer was +/- 10% on the weak beam, depending on the sample orientation.
