Abstract
The progress of holography as a useful optical technique for engineering applications is strongly dependent on the development of new recording materials having outstanding properties. Those materials must be prepared and processed following simple methods and they must give holograms of high diffraction efficiency value and a good signal to noise ratio. In the search of such a recording material, we studied photocrosslinking polymer systems as simple as dichromated poly (vinyl) alcohol films (DC-PVAL). Those films gave holograms having a maximum diffraction efficiency value (MDE) of 18% at 488 nm; at 442 nm, we obtained MDE values between 20% and 55%. When adding a xanthene dye, the MDE value can be increased. All of those results are obtained in real-time holography and the recording films were free of any chemical development. In the present communication we will introduce many new results on hologram recordings in XANTHENE DYE-DICHROMATED CASEIN films at 442 nm.
