Fluorite Crystals with Color Centers: A Medium for Recording Extremely Stable but Broadly Transformable Holograms
Description
The mechanisms of (i) forming the photochromic color centers in fluorite crystals (“additive coloring”) and (ii) recording and transforming holograms through the use of their photochromism are described here. The diffusion‐drift mechanism of hologram recording in additively colored fluorite crystals determines the recording kinetics and properties of holograms. An important feature of holograms recorded in additively colored fluorite is an opportunity to perform the photothermal transformation of color centers under the incoherent optical radiation that results in nondestructive switching of the hologram between the amplitude, amplitude‐phase (in‐phase or counter‐phase), and phase types at a given readout wavelength. Possible applications of holographic elements based on the additively colored fluorite crystals are discussed.
