cisterberg and W. Harguliz have demonstrated efficient generation of second harmonic waves in Ge-doped glass fibers with 1O64 nm light (1). This process is acompanied by an irreversible modification of the glass material tflat enhences the generation of Uie second harmonic and is induced by the presence of the second harmonic wave. We suggest a microscopic mechanism for the irreversible process.
