Highly efficient visible and UV light laser sources are of great importance for many applications. Visible emission can be obtained by frequency doubling in solid state lasers, using non-linear optical crystals. A particularly valuable recently developed non-linear optical crystals is GdCa4O(BO3)3 (GdCOB), grown by Czochralski technique, which is a non hygroscopic, easy to polish and of high hardness. In order to achieve high efficiency of second harmonic generation the crystals of high structural quality are needed. Crystal lattice defects are the source of lattice strains, which change the crystal optical properties, mainly the refractive indices.
