Abstract
A new method is studied for reading data that have been optically stored within the inhomogeneous spectral width of a material. The memory element is illuminated by a broad-bandwidth laser pulse. The signal that results from this excitation is analyzed by cross correlation with the field of a reference pulse, which is nothing but a delayed replica of the read pulse. Theoretical and experimental aspects of this process are discussed.
