Lithium niobate(LiNbO3)has been widely used in optical frequency converter, electro-optical modulator¡Asurface acoustic waveguide filter¡Aand photorefractive recording due to its ease of growth, high nonlinear coefficient, and excellent optical quality.
We think that we can utilize second harmonic generation (SHG) and laser scanning system to construct a reflective SHG system .From this system we can obtain PPLN poling pattern, then we can check the growth condition correctly or not. Compare to traditional method, this approach has the advantage of fast and non-invasive test. Besides, we can find crystal axis of crystal by changing the angle of incidence light and using additional half plate.
