You will find mainly two possible explanations for the powerful refractive index variation upon light irradiation: heating of the LiNbO3:Fe substrates and, Therefore, on the LC during the microchannel, and director reorientation in the electric industry induced by gentle inside the LiNbO3:Fe substrates. Now, up to now, just the refinement https://lithium-niobate-crystal02356.ampedpages.com/getting-my-lithium-niobate-crystal-to-work-59541969
