Photorefractive materials are well-suited for pattern observation since their intrinsically slow dynamics offers the opportunity to perform real-time measurements and observations. A single-feedback configuration creating two counterpropagating beams in the nonlinear optical medium gives rise to transverse modulational instability above a certain threshold. This instability generally leads to the formation of hexagonal patterns. In the case of the photorefractive feedback system, patterns of non-hexagonal geometry can be excited by changing the distance between the crystal and the feedback mirror. In addition, the powerful tool of spatial filtering can be applied to manipulate the system in a way that e.g. non-hexagonal patterns become dominant in a parameter region where the hexagon is the natural output of the system. From the point of view of all-optical image processing, this phenomenon can be interpreted as a distribution of a laser beam into an adaptive number of spots with the same intensity. Thus, switches from one to six, four or two channels can be realized. Taking into account higher order terms, other possible configurations of distributing channels are accessible. Our aim is to investigate the prospects of transmitting an image into these self-organized channels. We present experimental results for image transmission of simple geometric figures into the spatial sidebands, proving the principle function of our adaptive image processing system.

It has been shown in many occasions that the spontaneous emission rate of a dipolar radiative system can be strongly modified by the environment that surrounds it. Recently, it has been suggested that these changes could also be seen in very simple systems where the radiation is emitted only m one or two directions, as in surface second harmonic generation. In an experiment of SHG in front of a mirror, corresponding to the radiation of a sheet of dipoles at a variable distance from a surface boundary, Kauranen et al. [1998] observed that even when the total rate of radiation was suppressed, the field between the dipolar sheet and the boundary was finite and independent of this total rate. In this work, we have shown that this apparent contradiction can only be explained if the quadratic nonlinear interaction includes terms not conserving momentum, such as the term that considers the transfer of energy from the reflected SHG field to the incident fundamental and vice-versa.
在许多场合已经表明,偶极辐射系统的自发辐射率可以被它周围的环境强烈地改变。最近,有人提出,这些变化也可以在非常简单的系统中看到,其中辐射仅向一个或两个方向发射,如在表面二次谐波产生中。Kauranen et al.[1998]在镜面前的SHG实验中,对应于距离表面边界可变距离的偶极子片的辐射,观察到即使在总辐射率被抑制的情况下,偶极片和边界之间的场也是有限的,与总辐射率无关。在这项工作中,我们已经证明,这种明显的矛盾只能在二次非线性相互作用包含不守恒动量的项时才能解释,例如考虑从反射SHG场到入射基场的能量转移的项,反之亦然。

The interest in optical dipole traps as an elegant and simple way to store laser-cooled neutral atoms has rapidly increased. Far-off-resonance optical dipole traps can confine atoms in all ground states for a long time with a very small ground state relaxation time. In contrast to previous work, the magneto-optical trap presented here describes experiments performed with a few atoms, with the atom number ranging from 1 to 10. The precise control of a deterministic number of atoms is crucial in many experiments, e.g. in cavity QED and quantum information processing.

Summary form only given. Optical dipole traps facilitate storage of atoms independent of their magnetic sub-state. Trapping at high densities is thus not limited by two-body collisions changing the spin state of the atom, which in the particular case of cesium have so far prevented the attainment of Bose-Einstein condensation in magnetic traps. For evaporative cooling of Cs we use the gravito-optical surface trap (GOST) which consists of a horizontal evanescent-wave (EW) atom mirror in combination with a blue-detuned hollow beam (HE) for transverse confinement. Starting conditions for evaporative cooling are prepared by optical cooling, based on inelastic reflections from the EW.

Summary form only given. The dynamical behavior of two weakly mutually-coupled semiconductor lasers has been recently studied both experimentally and numerically. The main results predict that two different lasers may synchronize. The simplest synchronization mechanism is such that one laser is forced to oscillate at the relaxation oscillation frequency of the other laser. On the other hand, experiments on strongly mutually-coupled semiconductor lasers show the occurrence of synchronized low frequency fluctuations (LFFs) similar to the ones observed in a diode laser subjected to optical feedback. We numerically study the dynamical behavior of two mutually coupled semiconductor lasers under different coupling strengths and detunings. We model the two lasers with the single mode rate equations with extra terms accounting for the delayed light injected by the other laser. For simplicity, we take identical parameters for the two lasers, although for slightly different parameters we observe the same qualitative behaviors. We observe that for strong coupling and zero detuning both lasers exhibit synchronized LFFs.

The OCT system is capable of producing transversal as well as longitudinal images from the retina in vivo. A powerful superluminiscent diode at 860 nm is used, with the system delivering 140 /spl mu/W power to the eye.

The Coulomb field of an electron passing an atom generates a transverse electric field corresponding to a half cycle of electromagnetic radiation and a longitudinal field corresponding to a single cycle pulse. These fields induce transitions within the atom. The power spectrum of the radiation of a single-cycle pulse is very broad. The field of the passing electron can induce transitions in the atom to all states for which the energy difference to the initial state, /spl Delta/E, is within the generated power spectrum. As a result, collisional excitation lacks selectivity in the population of the excited states. We investigate how, in such a collisional process, the transfer to an excited state can be enhanced. In our search for a scheme to control the excited state population we are inspired by the success of controlled photoexcitation using narrow-band lasers, having many oscillations of the e.m. radiation field. We investigated if enhanced excitation of a selected state is also possible for electron collisions and thus turn the (inefficient) broadband excitation into controlled excitation to a selected final state. To this end we consider the impact of a train of electron pulses with a repetition frequency /spl nu/. As in the optical case, this will induce a series of N broadband bursts of radiation spectrum. As can be seen in the figure the analogy with photons holds and N electron bursts spaced with time /spl tau//sub r/ will also favour transitions with frequency /spl nu/=1//spl tau//sub t/.

Direct and powerful approaches for studying these interactions are footprinting and protein-DNA crosslinking formation. Protein-DNA crosslinking detects the presence of a protein on a given DNA sequence, while footprinting allows to study the mechanism of protein-DNA interactions.

Summary form only given. We demonstrate the application of a variable-coherence laser source for determining the scattering parameters of a diffuse medium and the potential for imaging spatially-dependent scatter. A key concept in this work in the ability to synthesize a variable-coherence source by frequency modulating a tunable laser diode (with a center wavelength of 850 nm) at a rate much faster than the integration time of the detector. This allows for a rapid measurement and the adaption of laser coherence to the degree of scatter, which we show is critical in obtaining the necessary sensitivity.

Coupled solid state laser systems belong to the wide family of nonlinear coupled oscillators. These systems are known to exhibit a great number of rich and complex dynamical behaviors: chaos, partial synchronization, periodic behavior, spiking. When the coupling strength is high enough, all the oscillators adopt a common and well defined phase relationship (phase locking). This state of "collective" order is very important since phase locked lasers are promising candidates for the delivering of high power coherent output. Starting from Maxwell-Bloch equations, we develop a theoretical model for a set of coupled monomode lasers in a single crystal. We adopt a semi-classical description and obtain a set of equations describing the temporal evolution of laser field amplitude and population inversion.
