Until the past few years, all materials showing the photorefractive effect were inorganic crystals," he says. With colleagues, he made the first observation of CW (continuous wave) laser harmonic generation and CW parametric amplification, discovered the photorefractive effect, and initiated the field of nonlinear optics in optical fibers. have developed the first polymer exhibiting the photorefractive effect. |
