“…III.A and B, but now regarded from a somewhat different angle, as being a direct consequence of Fresnel's equations. It should be noticed that this enhancement of the optical radiation pressure under total reflection condition was exploited by Komissarova et al in their experiments [3], and also in Ref. 22.…”

Asymmetric optical radiation pressure effects on liquid interfaces under intense illumination

Deformations of horizontal liquid interfaces by optical radiation pressure are generally expected to display similar behaviors whatever the direction of propagation of the exciting laser beam is. In the present experiment we find this expectation to be borne out, as long as the cw laser illumination is moderate in strength. However, as a striking contrast in the case of high field strengths, we find that either a large stable tether can be formed, or else that a break-up of the interface can occur, depending on whether the laser beam is upward or downward directed. Physically, the reason for this asymmetry can be traced to whether total reflection can occur or not. We also present two simple theoretical models, one based on geometrical optics, the other on wave optics, that are able to illustrate the essence of the effect. In the case leading to interface disruption our experimental results are compared with those obtained by Zhang and Chang for water droplets under intense laser pulses [Opt. Lett. 13, 916 (1988)]. A key point in our experimental investigations is to work with a near-critical liquid/liquid interface. The surface tension becomes therefore significantly reduced, which thus enhances the magnitude of the stationary deformations induced.

“…First attempts at observation of measurable liquid interface deformations by laser waves were performed with fairly high energy laser pulses [1][2][3] because the transfer of photon momentum to a dielectric interface is intrinsically weak and the corresponding pressure, which is proportional to the index contrast and the beam intensity, pushes against the Laplace pressure associated to interfacial tension. For example, Ashkin and Dziedzic [1] performed an experiment using a frequency doubled Nd:Yag laser (wavelength in vacuum λ 0 = 0.53µm) strongly focused on the water free-surface (beam waist value ω 0 = 2.1µm).…”

“…Since interface deformation also means lensing [1,4], these experiments strongly suggest the way to build adaptive optical blocks with fast switching response such as microlenses. That is why radiation pressure effects produced by pulsed lasers were extended to the recording of dynamic holograms [3]. Compared to thermallydriven surface relief distortions caused by surface tension gradients (also called Marangoni or thermo-capillary deformations [5,6]), which are used for infrared imaging [7] and hologram writing too [8], non thermal deformations produced by the radiation pressure have two main advantages: (i) energy is not dissipated and, (ii) the recording and the erasure rate are not determined by mass and thermal transport over the entire fluid layer (i.e.…”

We study the dynamics of the deformation of a soft liquid-liquid interface by the optical radiation pressure of a focused cw gaussian laser beam. We measured the temporal evolution of both the ranges, the small amplitude deformations are correctly described by a linear hydrodynamic theory predicting an overdamped dynamics. We also study the dynamics of the large amplitude interface deformations at the onset of the opto-hydrodynamic instability [Phys. Rev. Lett. 90, 144503 (2003)]. Using a simple, phenomenological model for the nonlinear evolution of the hump height, we interpret the observed interface dynamics at the instability onset as the signature of an imperfect subcritical instability.

“…The initial deformation is a direct result of the conservation of photon momentum as the photon encounters a boundary of differing refractive indices [12][13][14]. By solving for the simple case of a flat interface with normal incident photons (z-direction) on transparent media, we have for the momentum exchange…”

We introduce a noncontact purely optical approach to measuring the localized surface properties of an interface within a system using a single optical pressure pulse and a time-resolved digital holographic quantitative phase-imaging technique to track the propagating nanometric capillary disturbance. We demonstrate the proposed method's ability to measure the surface energy of deionized water, methanol, and chemical monolayers formed by surfactants with good agreement to published values. The development of this technique boasts immediate application to static and dynamic systems and near-future applications for living biological cell membranes.
