Abstract

The nanocrystallites (approximate to 3 nm) of $LiNbO_{3}$, evolved in the $(100-x)LiBO_{2}-xNb_{2}O_{5}$ (5 \leq x \leq 20, in molar ratio) glass system exhibited intense second-harmonic signals in transmission mode when exposed to infrared (IR) light at \lambda=1064 nm. The second-harmonic waves were found to undergo optical diffraction which was attributed to the presence of self-organized sub micrometer-sized $LiNbO_{3}$ crystallites that were grown within the glass matrix along the parallel damage fringes created by the IR laser radiation. Micro-Raman studies carried out on the laser-irradiated samples confirmed the self-organized crystallites to be $LiNbO_{3}$.
