Observation of non-degenerate photorefractive parametric amplification

    Research output: Contribution to journalJournal articleResearch


    We report on the first experimental observation of so-called nondegenerate photorefractive parametric amplification. We show that due to this effect it is possible for a weakly modulated photoinduced grating to be parametrically amplified via nonlinear interaction with a strongly modulated photoinduced grating.
