Abstract

Spectral hole burning media — photochemically i9stable dye molecules in low—temperature polymers hibit very narrow (10 Hz) optical resonances distributed over a wide (10 Hz) band along the frequency axis. Exposure of the medium to recording light field burns a 4—D grating pattern into the dielectric permittivity tensor c(x,y,z,), which in turn determines the temporal behaviour of the linear pulse response of the sample. Based on this phenomenon the common holography has been generalized resulting in a 4—D holography where restored light field is completely identical to the stored one and plays back ultrafast temporal behaviour of the object light as pulsed vector field. In the paper, the approach is extended for applications listed in the title and corresponding experimental results of streak —camera measurements on octaethyl—porphin —doped polystyrene plates are briefly discussed.
