Polarization instability of Raman solitons ejected during supercontinuum generation.

Optics express

Chao Q, Wagner KH.
PMID: 26832032
Opt Express. 2015 Dec 28;23(26):33691-704. doi: 10.1364/OE.23.033691.

We numerically investigate polarization instability of soliton fission and the polarization dynamics of Raman solitons ejected during supercontinuum generation in a photonics crystal fiber using the coupled vector generalized nonlinear Schrödinger equations for both linear and circular birefringent fibers....

Assessment of the adhesion quality of fusion-welded silicon wafers with nonlinear ultrasound.

Ultrasonics

Wegner A, Koka A, Janser K, Netzelmann U, Hirsekorn S, Arnold W.
PMID: 10829681
Ultrasonics. 2000 Mar;38(1):316-21. doi: 10.1016/s0041-624x(99)00096-7.

Diffusion bonded silicon wafers are employed in the semiconductor industry. Their bonding quality must be monitored by a nondestructive testing technique. We present an ultrasonic technique allowing us to monitor the quality of the diffusion bond by measuring the...

Doppler-free, multiwavelength acousto-optic deflector for two-photon addressing arrays of Rb atoms in a quantum information processor.

Applied optics

Kim S, Mcleod RR, Saffman M, Wagner KH.
PMID: 18404181
Appl Opt. 2008 Apr 10;47(11):1816-31. doi: 10.1364/ao.47.001816.

We demonstrate a dual wavelength acousto-optic deflector (AOD) designed to deflect two wavelengths to the same angles by driving with two RF frequencies. The AOD is designed as a beam scanner to address two-photon transitions in a two-dimensional array...

Sluggish light for radio-frequency true-time-delay applications with a large time-bandwidth product.

Optics letters

Gao L, Herriot SI, Wagner KH.
PMID: 17072423
Opt Lett. 2006 Nov 15;31(22):3360-2. doi: 10.1364/ol.31.003360.

A new radio-frequency (RF) photonic technique for achieving large RF time delays has been experimentally demonstrated using femtosecond pulses modulated by an acousto-optic tunable filter in a frequency-mapped and Doppler-shifted modulation scheme. A short optical delay line with length...

Variable-time-delay optical coherent transient signal processing.

Optics letters

Merkel KD, Babbitt WR, Anderson KE, Wagner KH.
PMID: 18079810
Opt Lett. 1999 Oct 15;24(20):1386-8. doi: 10.1364/ol.24.001386.

A technique is proposed and experimentally demonstrated that achieves simultaneous optical pattern waveform storage and programmable time delay for continuous real-time signal processing by use of optical coherent transient technology. We achieve variable-time-delay and broadband signal processing by frequency...

Eighth European meeting on hypertension.

Expert opinion on investigational drugs

Danser AH.
PMID: 15989669
Expert Opin Investig Drugs. 1997 Aug;6(8):1109-12. doi: 10.1517/13543784.6.8.1109.

The Eighth European Meeting on Hypertension, held in Milan, Italy, was attended by approximately 4000 people. The programme consisted of 120 presentations, 337 poster sessions, 6 invited lectures/debates (endothelin antagonists; cardiac renin-angiotensin system; cancer and hypertension; adducin; angiotensin converting...

Wide angular aperture holograms in photorefractive crystals by the use of orthogonally polarized write and read beams.

Applied optics

Sarto AW, Wagner KH, Weverka RT, Weaver S, Walge EK.
PMID: 21127587
Appl Opt. 1996 Oct 10;35(29):5765-75. doi: 10.1364/AO.35.005765.

We demonstrate a method of simultaneous holographic recording and readout in photorefractive crystals that provides high write-read beam isolation and wide angular bandwidth. The method uses orthogonally polarized read and write beams and parallel tangent diffraction geometry near the...

Doppler encoded excitation pattern tomographic optical microscopy.

Applied optics

Feldkhun D, Wagner KH.
PMID: 21124527
Appl Opt. 2010 Dec 01;49(34):H47-63. doi: 10.1364/AO.49.000H47.

Most far-field optical imaging systems rely on lenses and spatially resolved detection to probe distinct locations on the object. We describe and demonstrate a high-speed wide-field approach to imaging that instead measures the complex spatial Fourier transform of the...

Lipid oxidation of beef fillets during braising with different cooking oils.

Meat science

Saghir S, Wagner KH, Elmadfa I.
PMID: 22060918
Meat Sci. 2005 Nov;71(3):440-5. doi: 10.1016/j.meatsci.2005.03.021. Epub 2005 Jul 14.

Effects of braising without oil and with different cooking oils (olive oil, corn oil and partially hydrogenated plants oil) on the susceptibility to lipid oxidation in beef fillets (psoas major) were evaluated. The beef fillets were pan-fried without oil...

Fractionation of an Extract of Pluchea odorata Separates a Property Indicative for the Induction of Cell Plasticity from One That Inhibits a Neoplastic Phenotype.

Introduction. Several studies demonstrated that anti-inflammatory remedies exhibit excellent anti-neoplastic properties. An extract of Pluchea odorata (Asteraceae), which is used for wound healing and against inflammatory conditions, was fractionated and properties correlating to anti-neoplastic and wound healing effects were...
