Abstract
Ruby, Al2O3:Cr3+, is clearly an insulator, its electrical conductivity becoming finite only under optical excitation. Recently, the unusual photoelectrical properties of ruby have become a subject of considerable interest. A study has been carried out1 at a low (~ 10 K) temperature on crystals of concentrated ruby of the effect of intense Ar laser irradiation in the region of the broad U and Y absorption bands. A strong uniform electric field Es ~ 106 V/cm directed along the trigonal C axis was found to appear gradually and reach saturation in the excited region of the crystal: the field persisted after the pumping was turned off and the sample warmed up to room temperature.
