In centrosymmetric media, in addition to the thirdand fifth-order nonlinearity, a cascaded x :x (3) nonlinearity contributes to the nonlinear refraction. The described effect takes place when the input beam is involved in nearly phase-matched third-harmonic generation. The nonlinear phase shift produced by this new cascaded nonlinearity is comparable to the nonlinear phase shift caused by the direct third-order nonlinearity x . A new analytical approach, low depletion approximation, was developed and used to study the cascaded third-order processes in the conditions of not very high third-harmonic conversion coefficients. At higher conversion coefficients the effect was studied by numerical simulations. The presence of a seeded thirdharmonic wave gives another possibility of controlling the additional phase shift of the fundamental wave. The conditions for stationary copropagation of the fundamental and the generated wave are presented. @S1050-2947 ~98!01004-X#
在中心对称介质中，除了三阶和五阶非线性外，级联的x:x(3)非线性对非线性折射也有贡献。当输入光束参与近相位匹配的三次谐波产生时，所描述的效应就会发生。这种新的级联非线性产生的非线性相移与直接三阶非线性x引起的非线性相移相当。提出了一种新的分析方法——低损耗近似法，并将其用于研究三次谐波转换系数不是很高的情况下的级联三阶过程。在较高的转换系数下，通过数值模拟研究了这种效应。种子三谐波的存在提供了控制基波附加相移的另一种可能性。给出了基波与产生波平稳共传播的条件。@s1050——2947 ~ 98 !01004 - x #

Recently several proposals haw been made to m e a " the quantum &ate of the vibrational motion of a single trapped atom [I] and of a cavity radiation-mode [2,3]. On the other hand, we have propmed the mwurement of quasiprobability distributioits of a light mode via unbalanced homodyniq 141, where the determination of the quantum state is haved on a coherent displacement (due to the local millator) and the measurement of the photon-number statkticu. In the present mntribution we consider the application of similar methods for the determination of quasiprobability distributions for cavity fields and the motion of trapped atoms.

Wavelength scale periodic structures are of great current interest since they may be used to modify the interaction between light and matter [I]. In particular photonic band gaps may be used both to suppress [Z] and enhance [3] spontaneous emission. Recently we have studied band gaps for surface rather than bulk modes, and have shown that these may also be used to control spontaneous emission from a thin layer of dye 141. Such gaps occur when electromagnetic modes propagate on periodically modulated surfaces. We report on a detailed study to look at how the surface mode band structure depends on the surface profile. Our system comprised a corrugated metallic swfpce, fabricated using holographic techniques. Such a surface supports the propagation of surface plasmons. For M appropriate grating pitch Bragg scattering of the surface plasmon mode reds m the formation of a band gap. Using a convergent beam technique we are able to directly image the dispersion curve for the surface modes. With this technique we have determined how the band structure depends on the nature ofthe surface profile. The figure below shows how the width and central frequency of the gap valy as a hction of cormgation depth. The experimwtal data is seen to be well modelled by a recent theory [SI, indicated by the solid Line m the figures. The band gap described above only prohibits propagation over a small range of directions about the nod to the grating grooves. We have mersurcd how the band gap depends on the propagation direction and discuss the implications for the desiga of a photonic surface, ie one which prohibits the propagation of surface modes m all directions.
