14‐Fluoro‐Bacteriorhodopsin Gelation Films for Dynamic Holography Recording¶

Abstract

ABSTRACTThe 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.
