Femtosecond Laser Induced Growth of LiNbO3 Crystal in Glass

Abstract

Abstract: Crystal of LiNbO₃ was space-selectively induced in Li₂O-Nb₂O₅-SiO₂glass by using a focused femtosecond laser with high repetition rate. The light, which emits from the focal point of the laser, turns from white light to green-blue one as the laser irradiates for a few seconds. The luminescence spectra of the emission from the focal point demonstrate that the green-blue light is the second harmonic generation of the incident femtosecond laser. Micro-Raman spectra demonstrate that LiNbO₃ crystal is precipitated in the irradiated region of the glass.

Key words: LiNbO₃, glass, femtosecond laser
