- Abstract
Photothermal transformations of color centers in additively colored calcium fluoride crystals and in a colored crystal with a recorded hologram have been investigated. It is shown that the absorption spectrum of a colored crystal can be reconstructed within the entire transparency range of the matrix crystal by varying both factors affecting the sample-actinic radiation wavelength and temperature-as well as the duration of their effect. This possibility is important for the application of additively colored CaF crystals as a holographic medium.
