“…Beam coupling, in basic holography, is an unwanted effect because in thick crystals it can alter considerably the value of the modulation depth m along the direction of propagation of the light and, hence, the overall diffraction efficiency of the volume hologram. 16 One way to limit this effect is to make the scale of variation of the light intensity K small, thereby reducing the diffusive out-of-phase component of the hologram grating and applying an external voltage. Because TWM is at maximum approximately when K Х k Db (see, e.g., Ref.…”

“…Серед них утворення пучкiв з рiзною довжиною хвилi або частоти, оптичнi параметричнi пiдсилювачi та осцилятори, обертання хвильового фронту, створення голографiчних зображень, обробка оптичних сигналiв та зображень тощо [1]. Разом з генерацiєю компонент рiзної довжини хвилi або частоти, пiдсиленням та осциляцiями, в останнi роки було показано, що при взаємодiї хвиль утворюються стiйки просторово-часовi локалiзованi стани [2][3][4][5][6]. Цей ефект спостерiгається при самодифракцiї хвиль на динамiчних ґратках, якщо збуджуюча "свiтлова ґратка" iнтерференцiйної картини та динамiчна ґратка показника заломлення зсунутi у просторi одна вiдносно iншої.…”

“…This brings an additional phase shift between the transmitted and diffracted waves during their interference in the medium. The intensity ratio of input waves is a control parameter, which defines the magnitude of the energy transfer and amplification coefficient for a signal wave [13][14][15].…”
