✦ Synopsis
A glass of Li 2 O-Nb 2 O 5 -SiO 2 -B 2 O 3 with an addition of CuO or Sm 2 O 3 crystallizing in nonlinear optical lithium niobate LiNbO 3 is developed. Crystalline lines of Lithium Niobate have been fabricated by continuous wave laser irradiation of the glass surface. The crystalline laser written lines have been found, by means of micro-Raman and Second Harmonic experiments, to be well oriented with its c-axis pointing along the laser scanning direction. The analysis of the confocal micro luminescence spectra obtained at the crystalline line have confirmed the incorporation of rare-earth ions in the crystalline network.
