Photothermal poling of glass complexes Ag2S–Ga2S3–P2S5

The studies of the dc-electric field induced second harmonic generation (SHG) for fundamental wavelength of the Ag2S–Ga2S3–P2S5 using nanosecond Er:glass laser at wavelength 1540nm and elevated temperatures (thermal poling) were performed. We have found that the highest output SHG efficiency is obta...

Summary:The studies of the dc-electric field induced second harmonic generation (SHG) for fundamental wavelength of the Ag2S–Ga2S3–P2S5 using nanosecond Er:glass laser at wavelength 1540nm and elevated temperatures (thermal poling) were performed. We have found that the highest output SHG efficiency is obtained for the maximal Ga2S3 content and with simultaneous presence of Ag2S. We have shown that the SHG effect exists only during simultaneous dc- and thermal poling at about 120°C. After switching off of the dc-electric field the effect is completely reversible. The maximally achieved value of the effective second-order optical susceptibility is equal to about 0.75pm/V at 1540nm wavelength, which allows to propose to apply these materials for the laser operation.
