Abstract :
Second harmonic generation (SHG) in poled glasses opens new opportunities in material research and device development for optics. Within this context (1−x)LaMgB5O10–xTiO2 and (1−x)LaMgB5O10–xNb2O5 (0⩽x⩽0.4) glasses have been formed and characterized. The structure of unpoled glasses has been studied by IR, Raman, and XAFS spectroscopies. Optical properties of transmission like linear refractive indexes and third-order non-linear optical susceptibility χ(3) have been investigated. A second harmonic signal was observed for each thermally poled composition, except for the LaMgB5O10 matrix glass.
