Abstract

Real-time recording of a moving object was made with persistent spectral hole burning of a cryogenic Eu3+:Y2SiO5 crystal. In a basic holographic configuration the ultrastable laser frequency was continuously scanned within the 7F05D0 absorption line (typically 200 MHz in 20 s) while the object was in motion, thus permitting the storage and reconstruction of the moving image. The success of this motion picture is attributable to (1) the kilohertz-wide hole width, (2) the quasi-persistent hole lifetime, and (3) the high hole-burning quantum efficiency of this material.

Hole-burning spectra obtained by various readout methods—transmission, luminescence, and holography—for the 7F05D0 transition of Eu3+:Y2SiO5 at T = 7 K. First, a hole was burned by application of a burn laser of a fixed frequency for 50 ms. Then the probe laser was scanned only once (no averaging) while the transmitted power, the photoluminescence (PL) intensity, and the diffracted power were detected for each measurement.
