Abstract

We have observed long-term storage and phase conjugation of multiple images by using a backward-stimulated echo scheme in the ³H₄–³P₀ transition of Pr³⁺:LaF₃ crystal. The temporal order of the multiple-echo images is the reverse of that of the input images. Each of the echo images is a phase-conjugate replica of the input images and lasts as long as 15 sec. This constitutes, in principle, the first reported demonstration of an ultrafast holographic movie using a stimulated photon echo.
