Abstract

The precursor glasses in (mol%) 25.53Li2O-21.53Ta2O5- 35.29SiO2-17.65Al2O3 (LTSA) and 25K2O-25Nb2O5-50SiO2 (KNS) glass systems were prepared by the melt-quench technique. Ferroelectric LiTaO3 (LT) and KNbO3 (KN) crystallites containing bulk nano glass-ceramics have been prepared by controlled crystallization of these precursor glasses respectively. Second harmonic generations (SHG) at 532 nm in both the glass-ceramics have been realized under fundamental beam of Nd3+:YAG laser source (1064 nm). The SHG power output has been found to increase up to 14 and 62.4 nJ with variation of rotation angle for LT and KN bulk nano glassceramics respectively due to orientation of ferroelectric domains under applied field.
