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.
The photorefractive effect is caused by traces of impurities and minor crystal defects, which supply the crystal with extra electrical charges trapped within the material.
