Two strains of Streptococcus pneumoniae, M4 (NCTC 7465, type strain) and M5 (clinical isolate), and their respective ciprofloxacin-resistant mutants, M4/C1, M5/C1 and M5/C3, were evaluated. All mutants were stable after one year's storage and all gre

The dynamics of a relativistic plasma wave (RPW) resonantly excited by a two frequency CO2 laser pulse and the effects of this wave on a co-propagating relativistic electron beam were studied through experiments and supporting simulations. The amplit

A Lagrangian fluid model (cold plasma, fixed ions) is developed for analyzing the coupling between electron plasma waves. This model shows that a small wave number electron plasma wave (ω2,k2) will strongly affect a large wave number electron plasma

Experimental evidence for the coupling between two electron plasma waves having nearly the same frequency but greatly differing in wave number is presented using time and wave-number resolved spectra of Thomson scattered light from the plasma. The qu

Experimental evidence for the evolution of stimulated Raman backscatter instability of laser light into stimulated Compton scattering in an initially cold plasma is presented using time and wave number resolved spectra, [ital w]([ital t]) and [ital w

The results from experiments in which a two‐frequency CO2 laser is used to beat‐excite large‐amplitude, relativistic electron plasma waves in a tunnel‐ionized plasma are reported. The plasma wave is diagnosed by injecting a beam of 2 MeV elec

High-gradient acceleration of externally injected 2.1-MeV electrons by a laser beat wave driven relativistic plasma wave has been demonstrated for the first time. Electrons with energies up to the detection limit of 9.1 MeV were detected when such a

We present here the first in vivo optical coherence tomography (OCT) images of human dental tissue. A novel dental optical coherence tomography system has been developed. This system incorporates the interferometer sample arm and transverse scanning

We demonstrate cross-sectional birefringence- and polarization-independent backscatter imaging of laser-induced thermal damage in porcine myocardium in vitro, using a polarization-sensitive optical coherence tomography system. We compare the generate
