Photorefractive effect in lithium niobate crystals

P JAYANTH, C K SUBRAMANIAN

Abstract


Phase-grating formation in Iron-doped lithium niobate crystal was studied. Growth is observed to be oscillatory with a time period of over several seconds; oscillatory growth had intenslty variations of smaller time scales overriding it.

Keywords


Nonlinear Optics; photorefractive crystals; phase conjugation.
