Holographie wird im allgemeinen als eine photographische Methode angesehen, mit der ein dreidimensionales Bild von einem Objekt erhalten werden kann. Dies ist sicherlich der spektakularste Aspekt. Holographie kann jedoch auch als eine besonders leist

It is demonstrated that the microscopic mechanism of the photorefractive (PR) effect in organic composites with low glass transition temperatures involves the formation of refractive index gratings through a space‐charge field‐modulated Kerr effe

The performance of amorphous organic photorefractive (PR) materials in applications such as optical data storage is generally limited by the concentration of active molecules (chromophores) that can be incorporated into the host without forming a cry

Holographic data recording appears to have several advantages over conventional optical and magnetic recording methods [1].[2] A high read/write rate can be achieved by utilizing massively parallel reading and writing schemes. High storage density ca

A photorefractive system is one which is simultaneously photoconductive and electrooptic. Diffraction gratings or holograms can be produced in a photorefractive material by the photogeneration, drift or diffusion and subsequent trapping of mobile cha

The nonlinear susceptibility of acetonitrile has been measured in both the gas and liquid phases by dc electric field‐induced second harmonic generation (dc‐SHG or EFISH). The EFISH signal for this molecule is dominated by the first hyperpolariza

Frequently it is useful to compare experimental values of the hyperpolarizabilities β and γ with calculated values. It is also often helpful to compare experimental values of β obtained from dc‐electric field induced second harmonic generation (

The initial steps involved in the charge separation process in thin films of the organic charge-transfer complex formed from poly-N-vinylcarbazole (PVK) and 2,4,7-trinitro-9-fluorenone (TNF) are observed directly using polarization selective pico-sec

Values of the second order hyperpolarizability β have been determined for p-nitroaniline (PNA) in solvents of varying polarity using the electric field induced second harmonic generation experimental technique. An observed solvent dependence of β0,
