Abstract
Today the efforts are made to create compact, high-speed optical echo-processors with high information capacity. Compactness may be achieved using solid-state information carriers, which must be cheap also. Dye-doped polyvinylbutural films are numbered among such information carriers. The first dynamic hologram recording in a photon-echo regime in such films was realised in experiment at the liquid helium temperature what restrained this material applications to echo-processors. We have demonstrated the echo-hologram recording in above films at room temperature by use of femtosecond pulses. Therefore, the dye-doped polyvinylbutural film may be considered as one of the candidates to be applied to optical information processing devices.
