High power, pulsed microwaves are beamed forward of a model in a Mach 6 flow using an on-board, Ku-band horn. A thin “precursor” plasma is generated just ahead of the bow shock in the low density free stream. Temporal and spatial analysis of the

A model for stimulated Raman scattering in the atmosphere is described for the pure rotational transitions in N(2). This model accounts for the wavelength dependence of the N(2) polarizability anisotropy, altitude and seasonal temperature variations

We report what is to our knowledge the first two-photon-excited fluorescence spectroscopy of atomic fluorine. A doubled dye laser at 286 nm is Raman shifted in H(2) to 170 nm (sixth anti-Stokes order) to excite ground-state (2)P degrees (J) fluorine

We demonstrate the use of a novel technique for the detection of heterodyne laser-induced thermal acoustic signals that allows the construction of a highly stable seedless laser velocimeter. A common-path configuration is combined with quadrature det

An application of focal-plane imaging that can be used as a real time diagnostic of beam crossing in various optical techniques is reported. We discuss two specific versions and demonstrate the capability of maximizing system performance with an exam

A unified discussion on coherent light scattering spectroscopy and its spectral dependence on molecular gas velocity, temperature and density is presented. The feasibility of using coherent Raman spectroscopy techniques for nonintrusive measurements

The temperature and density dependence of the rotational Raman linewidths and line shifts for the diatomic molecules ${\mathrm{N}}_{2}$ and ${\mathrm{H}}_{2}$ has been measured using stimulated Raman gain spectroscopy. Room-temperature results for th

Stimulated Rayleigh-Brillouin gain spectra of pure gases are reported. Stimulated Rayleigh scattering is now clearly distinguishable from stimulated Brillouin scattering without the aid of induced absorption. As examples, spectral line shapes of Ar a
