Paper Abstract

With a conventional degenerate four-wave mixing (um) configuration, the gelatin film containing fluorescein, erythrosin or eosin produces the phase conjugate CPC1 wave by not only the DFWM process but also the holographic process at the intensity of lower than 0.5 w/cm2 of light emitted by a cw Arion laser1). The holographic process differs from the DFWMprocess in the respect that light incident on a dye-doped film induces permanent photochemical changes in the absorption and/or the refractive index. The distinction between the two process is more clearly brought out in the response time of the PC wave by each process: the DFWM component with a fast response time of the order of milliseconds and the holographic component with a slow response time of the order of minutes2),3) Our aim is to demonstrate that a gelatin film containing methylreds can generate the PC wave only by the DFWM process, but a PMMA film containing methylreds can generate the PC waves by the DFWM and holographic processes.
