Franke P, Turnbull D, Katz J, Palastro JP, Begishev IA, Bromage J, Shaw JL, Boni R, Froula DH.
PMID: 31684419
Opt Express. 2019 Oct 28;27(22):31978-31988. doi: 10.1364/OE.27.031978.

Large diameter, flying focus driven ionization waves of arbitrary velocity (IWAV's) were produced by a defocused laser beam in a hydrogen gas jet, and their spatial and temporal electron density characteristics were measured using a novel, spectrally resolved interferometry...

Single-shot high-resolution characterization of optical pulses by spectral phase diversity.

Optics express

Dorrer C, Waxer LJ, Kalb A, Hill EM, Bromage J.
PMID: 26831979
Opt Express. 2015 Dec 28;23(26):33116-29. doi: 10.1364/OE.23.033116.

The concept of spectral phase diversity is proposed and applied to the temporal characterization of optical pulses. The experimental trace is composed of the measured power of a plurality of ancillary optical pulses derived from the pulse under test...

Offner radial group delay compensator for ultra-broadband laser beam transport.

Optics letters

Bahk SW, Bromage J, Zuegel JD.
PMID: 24562283
Opt Lett. 2014 Feb 15;39(4):1081-4. doi: 10.1364/OL.39.001081.

Conventional lens-based image relays introduce radial group delay that significantly reduces focal-spot intensity of ultra-broadband short pulses. A direct compensation scheme that can be used with conventional singlet image relays is proposed. The compensation scheme is based on using...

Highly sensitive, single-shot characterization for pulse widths from 0.4 to 85 ps using electro-optic shearing interferometry.

Optics letters

Bromage J, Dorrer C, Begishev IA, Usechak NG, Zuegel JD.
PMID: 17099771
Opt Lett. 2006 Dec 01;31(23):3523-5. doi: 10.1364/ol.31.003523.

Single-shot characterization using electro-optic shearing interferometry (EOSI) is shown for pulse widths ranging from their transform limit (0.4 ps) to 200x their limit (85 ps). In EOSI, the spectral phase is reconstructed by interfering two spectrally sheared replicas of...

Matrix isolation studies and DFT calculations on molecular alkali metal bromates.

Physical chemistry chemical physics : PCCP

Ogden JS, Graham JT, Joy JT, Ferrante F.
PMID: 19835086
Phys Chem Chem Phys. 2009 Jan 28;11(4):650-4. doi: 10.1039/b813021c.

DFT and MP2 calculations have been carried out on a series of molecular alkali metal bromates MBrO3 (M = Na, K, Rb, Cs), and the results compared with matrix isolation IR studies on the vaporisation of the solid salts....

Pb4(OH)4(BrO3)3(NO3): An Example of SHG Crystal in Metal Bromates Containing π-Conjugated Planar Triangle.

Inorganic chemistry

Kong F, Hu CL, Liang ML, Mao JG.
PMID: 26689494
Inorg Chem. 2016 Jan 19;55(2):948-55. doi: 10.1021/acs.inorgchem.5b02523. Epub 2015 Dec 21.

The first example of SHG crystal in the metal bromates containing π-conjugated planar triangle systems, namely, Pb4(OH)4(BrO3)3(NO3), was successfully synthesized via the hydrothermal method. Furthermore, a single crystal of centrosymmetric Pb8O(OH)6(BrO3)6(NO3)2·H2O was also obtained. Both compounds contain similar [Pb4(OH)4]...

Self-phase modulation compensation in a regenerative amplifier using cascaded second-order nonlinearities.

Optics letters

Dorrer C, Roides RG, Bromage J, Zuegel JD.
PMID: 25078204
Opt Lett. 2014 Aug 01;39(15):4466-9. doi: 10.1364/OL.39.004466.

Self-phase modulation limits the amplification of short optical pulses because of spatial self-focusing and spectral broadening. Cascaded nonlinearities are theoretically and experimentally investigated for intracavity nonlinearity compensation in a neodymium-doped yttrium-lithium-fluoride (Nd:YLF) regenerative amplifier. Experimental results are in good...

Theor Appl Genet. 1995 Feb;90(2):205-10. doi: 10.1007/BF00222203.

Androgenesis is a potentially valuable technique for recovering fish from gene banks composed of cryopreserved sperm, developing inbred lines, and analyzing patterns of inheritance. The procedure for producing diploid organisms whose nuclear DNA is wholly of paternal origin is...

AIMS: Patients hospitalized for heart failure (HF) had worse in-hospital outcomes during the first wave of the COVID-19 pandemic. However, their long-term outcomes are unknown. We describe long-term outcomes among patients who survived to hospital discharge compared with patients...
