ABSTRACT

The first dynamic holography recording using 14-fluoro-(14-F) bacteriorhodopsin (BR) gelatin films has been achieved. 14-F BR is an artifical BR pigment made by reconstitution of bacterioopsin (native BR without chromophore) with synthetic 14-F ratinal. Low-intensity red light from a cw HE-Ne laser was used for dynamic holography recording on the 14-F wild type (WT) BR and 14-F D96N mutant BR in gelatin films. There is not true comparing the diffraction efficiency for 14-F D96N BR and 14-F WT gelatin film, unlike the increase diffraction efficiency for D96N BR gelation film with native chromphore relative to the WT BR gelatin film with native chromophore. Pre-illumination with blue light of the 14-F BR gelatin films significantly increases the differaction effciency of both the the 14-F WT and the 14-F D96N BR pigments. The sequential application of blue and red laser beams indicates that 14-F WT and the 14-F D96N BR pigments. The sequential application of blue and red laser beams indicates taht 14-F BR gelation films can be useful for optical memory.
