| Popis: | Measured are the unwanted additional phase change between two components of phase-conjugate (PC) signals, the saturable absorption and holographic components, simultaneously generated in a real-time PC interferometry with an erythrosin B-doped polyvinyl alcohol film used as a PC mirror. For the pump and probe intensities of 1 W/cm 2 and 0.3 W/cm 2 and optical density of 1.8, the unwanted additional phase change was less than about π/4 within 5 min for the hologram-recording times of 15 s, 30 s and 60 s, and less than about π/8 for the hologram-recording time of 120 s. The temperature rise of the irradiated dye-doped film was mainly responsible for the unwanted additional phase change. |
