Thermally poled new borate glasses for second harmonic generation

Second harmonic generation (SHG) in poled glasses opens new opportunities in material research and device development for optics. Within this context (1− x)LaMgB 5O 10– xTiO 2 and (1−x) LaMgB 5 O 10–x Nb 2 O 5 (0⩽x⩽0.4) glasses have been formed and characterized. The structure of unpoled glasses has...

Zusammenfassung:	Second harmonic generation (SHG) in poled glasses opens new opportunities in material research and device development for optics. Within this context (1− x)LaMgB 5O 10– xTiO 2 and (1−x) LaMgB 5 O 10–x Nb 2 O 5 (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 LaMgB 5O 10 matrix glass.
