Abstract
An application of a dye solution for wavefront multiplication is described. In this application, two coherent pumping laser beams generate a spatial gain and index‐of‐refraction distribution in a dye amplifier. This distribution is used to modulate the amplitude and phase of an optical field in the amplification band of the dye in order to form a new wavefront. To establish that the multiplication is due to singlet‐state effects and not to triplet‐state excitation, the lifetime of the information in the dye cell is measured.Keywords
