Nonlinear Propagation in Multimode Fibers with Random Mode Coupling
No full textWe present the generalized Manakov equations describing nonlinear propagation in multimode and multicore fiber structures in the presence of random mode coupling and show how they can be extended to model multimode Raman amplification
Estimation of vibration amplitude in Fourier domain optical coherence tomography interferometric signals from Doppler spectrum
No full textIn presented method combination of Fourier and Time domain detection enables to broaden the effective bandwidth for time dependent Doppler Signal that allows for using higher-order Bessel functions to calculate unambiguously the vibration amplitudes
Book Review, Environmental Law
No full textReviews a hornbook published by West Publishing Company. The author begins by criticizing the authors for giving little attention to what the author believes might be the most important topic in environmental law—population control. In total, however, the author finds that this book is a competent attempt to effectively cover a large subject matter

Fast Fourier-Transform Second-Harmonic Generation (FFT-SHG) Provides a Solution for Measuring Nonlinear Effects on Fragile Structures
No full textThe intense laser power required to measure nonlinear effects can damage the structures upon measuring. We demonstrate that fast Fourier-transform second-harmonic generation (FFT-SHG) technique provides an elegant solution to obtain polarization patterns of degrading structures.status: Publishe
Recent Progress in Quantum Imaging and Ghost Imaging
No full textWe summarize recent work that demonstrates the utility of quantum effects for important technological applications in image science. We emphasize that what was considered to be “quantum weirdness” only a few years ago is today useful technology
Visualizing Quantum State Rotations through Weak Measurements of Orbital Angular Momentum
No full textUsing the technique of direct measurement, we observe the action of the angular momentum operator as the generator of rotations. Our method employs weak measurements of orbital angular momentum and strong measurements of angular position
Multi-scale Multi-contrast Photoacoustic Microscopy
No full textPhotoacoustic microscopy (PAM) is a hybrid imaging technique that acoustically detects optical contrast via the photoacoustic effect. With its excellent scalability, PAM can simultaneously image anatomical, functional, molecular, flow dynamic, and metabolic contrasts in vivo
Technology developments for ACIGA high power test facility for advanced interferometry
No full textCopyright © Institute of Physics and IOP Publishing Limited 2005.The High Optical Power Test Facility for Advanced Interferometry has been built by the Australian Consortium for Interferometric Gravitational Astronomy north of Perth in Western Australia. An 80 m suspended cavity has been prepared in collaboration with LIGO, where a set of experiments to test suspension control and thermal compensation will soon take place. Future experiments will investigate radiation pressure instabilities and optical spring effects in a high power optical cavity with ~200 kW circulating power. The facility combines research and development undertaken by all consortium members, whose latest results are presented.P Barriga, M Barton, D G Blair, A Brooks, R Burman, R Burston, E J Chin, J Chow, D Coward, B Cusack, G de Vine, J Degallaix, J C Dumas, M Feat, S Gras, M Gray, M Hamilton, D Hosken, E Howell, J S Jacob, L Ju, T L Kelly, B H Lee, C Y Lee, K T Lee, A Lun, D E McClelland, K McKenzie, C Mow-Lowry, A Moylan, D Mudge, J Munch, D Rabeling, D Reitze, A Romann, S Schediwy, S M Scott, A Searle, B S Sheard, B J J Slagmolen, P Veitch, J Winterflood, A Woolley, Z Yan and C Zha
