Holographic Methods for Investigating Solid-State Photochemistry

The conventional recording of holographic images in a solid substrate may be thought of as a four-wave mixing process in which the resulting interference pattern is not transient, as in more conventional four-wave mixing experiments, but is permanent. in this paper, we describe the use of holographic techniques to obtain detailed information on solid-state photochemical processes. We describe two experiments in detail: the determination of quantum yields and the measurement of polymer chain lengths. Copyright © 1986 by The Institute of Electrical and Electronics Engineers, Inc.
