Abstract

An erythrosin-doped polyvinyl alcohol (PVA) film can generate phase-conjugate (PC) waves simultaneously by degenerate four-wave mixing (DFWM) process with a fast response time and holographic process with a slow one. The DFWM component with a response time of about 1 msec results from saturable absorption in erythrosin dyes, while the holographic component with a response time of tens sec is generated from a hologram recorded in the erythrosin/ PVA film. The PC reflectivities for both components exceed one percent. In combination of these two processes, we demonstrate that the erythrosin/PVA film is available for real-time and double exposure PC interferometries with a cw argonion laser.
