Noncontact Control by Laser Conoscopy of Optical Homogeneity of Heavily Doped LiNbO3: Zn
A non-contact method using laser conoscope the studies of optical homogeneity of a series of heavily doped LiNbO3 crystals (4.46–4.69 mol. % ZnO). For all crystals not detected additional anomalies in сonoscopic patterns at increase of laser radiation power up to 90 mW, due to the presence of static and fluctuating defects induced in the photorefractive crystal by laser radiation.
