Electronic spectral parameters and IR nonlinear optical features of novel Ag0.5Pb1.75GeS4 crystal

Popis výsledku v původním jazyce

In this paper, we report on novel Ag0.5Pb1.75GeS4 single crystals grown by the Bridgman-Stockbarger method. For these crystals we have performed X-ray photoelectron spectroscopy (XPS) studies of the valence-band and core-level electron states. Second harmonic generation efficiency of Ag0.5Pb1.75GeS4 powder samples by using CO2 laser light depending on the power density up to 1100 MW/cm(2) has been obtained within the temperature range 77-520 K. The obtained dependences indicate relatively strong enhancement of photoinduced SHG output efficiencies as temperature increases. Both the spectra taken at ambient and 520 K temperatures have shown similar behavior-rapid growth to saturated values of SHG efficiency with an increase of fundamental beam power density up to 400 MW/cm(2), then slowly decreasing with power density reaching a value of 800 MW/cm(2) and finally these features show a second small maximum at a fundamental beam power density equal to 900 MW/cm(2). Beyond this power density
