Dynamic hologram magnification with incoherent optical pumping

Abstract

In the present work consideration is given to theoretical and experimental analysis of the possibilities for improving the efficiency of multiwave mixing in the process of dynamic hologram recording in solutions of complex organic compounds with additional irradiation of resonant medium at a frequency falling within the absorption band from the excited level. Three- and seven-fold increase in the diffraction efficiency has been realized in Rhodamine 6G dye for four- and six-wave missing, respectively.
