Refractive-index profiling of optical fibers with axial symmetry by use of quantitative phase microscopy.

Optics letters

Roberts A, Ampem-Lassen E, Barty A, Nugent KA, Baxter GW, Dragomir NM, Huntington ST.
PMID: 18033441
Opt Lett. 2002 Dec 02;27(23):2061-3. doi: 10.1364/ol.27.002061.

The application of quantitative phase microscopy to refractive-index profiling of optical fibers is demonstrated. Phase images of axially symmetric optical fibers immersed in index-matching fluid are obtained, and the inverse Abel transform is used to obtain the radial refractive-index...

Thermal eigenmode amplifiers for diffraction-limited amplification of ultrashort pulses.

Optics letters

Salin F, Blanc CL, Squier J, Barty C.
PMID: 18087320
Opt Lett. 1998;23(9):718-20. doi: 10.1364/ol.23.000718.

The design of high-repetition, high-average power, multipass amplifiers in which the pump power induced thermal lensing within the amplifier is used to create an equivalent lens waveguide for the production of diffraction-limited beams is analyzed.

Attention-Deficit/Hyperactivity Disorder and the challenges of close friendship.

Journal of the Canadian Academy of Child and Adolescent Psychiatry = Journal de l'Academie canadienne de psychiatrie de l'enfant et de l'adolescent

Normand S, Schneider BH, Robaey P.
PMID: 18392154
J Can Acad Child Adolesc Psychiatry. 2007 May;16(2):67-73.

INTRODUCTION: Much has been learned about the social rejection of children with Attention-Deficit Hyperactivity Disorder (ADHD) by their schoolmates. Although these group processes are clearly important, recent advances in theory and research have revealed the importance of close friendship.METHOD:...

A 50 EW/cm;2 Ti:sapphire laser system for studying relativistic light-matter interactions.

Optics express

Walker B, Toth C, Fittinghoff D, Guo T, Kim DE, Rose-Petruck C, Squier J, Yamakawa K, Wilson K, Barty C.
PMID: 19401724
Opt Express. 1999 Nov 08;5(10):196-202. doi: 10.1364/oe.5.000196.

A 10-Hz repetition rate, 60-TW peak power, Ti:sapphire laser system was developed for use in experiments where relativistic effects dominate the physics. The temporal, spectral, energy and spatial characteristics of the laser pulses were measured in single shot format....

Performance evaluation for long-range turbulence-detection using ultraviolet lidar.

Applied optics

Feneyrou P, Lehureau JC, Barny H.
PMID: 19571933
Appl Opt. 2009 Jul 01;48(19):3750-9. doi: 10.1364/ao.48.003750.

Clear-air turbulence could be detected at long range using a UV lidar. Because the vertical speed cannot be retrieved from Doppler shift analysis at long range, the turbulence detection is based on the measurement of molecular density fluctuation associated...

Presurgical nasoalveolar moulding treatment in cleft lip and palate patients.

Indian journal of plastic surgery : official publication of the Association of Plastic Surgeons of India

Grayson BH, Shetye PR.
PMID: 19884682
Indian J Plast Surg. 2009 Oct;42:S56-61. doi: 10.4103/0970-0358.57188.

Presurgical infant orthopedics has been employed since 1950 as an adjunctive neonatal therapy for the correction of cleft lip and palate. Most of these therapies did not address deformity of the nasal cartilage in unilateral and bilateral cleft lip...

PMID: 18264320
Appl Opt. 1997 Oct 20;36(30):7919-28. doi: 10.1364/ao.36.007919.

The beam attenuation coefficient is an optical parameter that sensitively depends on suspended and dissolved substances in water. Its measurement is not only of interest for an understanding of the radiative transfer in a water column. With appropriate algorithms...

Phys Chem Chem Phys. 2011 May 14;13(18):8441-7. doi: 10.1039/c0cp02472d. Epub 2011 Feb 28.

The production of a translationally cold (T < 1 K) sample of bromine atoms with estimated densities of up to 10(8) cm(-3) using photodissociation is presented. A molecular beam of Br(2) seeded in Kr is photodissociated into Br +...

Cortical information flow during inferences of agency.

Frontiers in human neuroscience

Dogge M, Hofman D, Boersma M, Dijkerman HC, Aarts H.
PMID: 25177282
Front Hum Neurosci. 2014 Aug 14;8:609. doi: 10.3389/fnhum.2014.00609. eCollection 2014.

Building on the recent finding that agency experiences do not merely rely on sensorimotor information but also on cognitive cues, this exploratory study uses electroencephalographic recordings to examine functional connectivity during agency inference processing in a setting where action...
