A large photoinduced reversible change of third-harmonic generation in azo-dye polymer thin films was recently observed. In this work, the microscopic interpretation of this phenomenon is given. The model presented is based on an angular hole burning

An efficient second harmonic generation in the quadratic polarizability gratings (χ(2)-gratings) written in lead-containing glasses based on barium, strontium, and calcium metaphosphates has been observed. It is shown that the generation efficiency

The influence of cerium impurities on the efficiency and the rates of formation and decay of the photoinduced second harmonic generation in lead-containing glasses based on barium metaphosphate is experimentally investigated. It is shown that introdu

Optically induced second harmonic generation in lead–phosphate glasses has been observed. The efficiency of conversion to second harmonic in lead–phosphate glasses was of the same order of magnitude as in lead–silicate glasses. Growth and decay

The authors explored tensor properties of chi (2) gratings induced in bulk glass under different polarization conditions. Three cases were studied: recording of gratings by waves with parallel, orthogonal and 45 degrees -tilted polarizations. The res

A new method for the measurement of the phase shift between second-harmonic light generated by a bulk glass and the injected second-harmonic seed is presented. A linearly polarized pump and a second-harmonic seed with noncollinear polarizations were

A new method for readout of χ(2)-holograms recorded by noncollinearly polarized light beams of different frequencies is proposed and implemented. The hologram is read out and recorded simultaneously by the same reference beam, thus eliminating any i

The tensor properties of χ(2) gratings written in bulk glass have been studied for various polarization conditions. Three basic cases were studied: the writing of gratings by waves with parallel polarizations, perpendicular polarizations, and polari
