Formation of RDX nanoparticles by rapid expansion of supercritical solution : in situ characterization by laser scattering
… CO_2 were characterized in situ by a pulse laser light scattering imaging technique using gated ICCD camera. The sensitivity was determined using Rayleigh scattering from air as well as light scattering from standard polystyrene spheres. The size distribution functions of the particles …

Quantitative non-destructive study of sub-micron defects in very large scale integrated-circuit silicon using transmitted and reflected infra-red laser scattering
"The limits and capabilities of the Scanning Infra-Red Microscope (SIRM) and the Optical Precipitate Profiler (OPP) to detect oxygen precipitate defects in silicon were investigated. Two sets of specimens were made and studied. One set had wafers containing the same bulk defect density, but had …

Radiative heat transfer from aluminum oxide in solid propellant flames
… of aluminized propellant flames. A laser scattering and extinction technique was developed to determine the optical properties of liquid Al$\sb2$O$\sb3$ in the propellant flames at two wavelengths. Optical properties consisted of the real and imaginary parts of the complex index of …

DIAGNOSTICS AND REAL-TIME MONITORING OF PULSED LASER ABLATION
… and real-time monitoring during pulsed laser ablation of solid materials are investigated. It is found that acoustic, optical and electric signals generated are closely related to laser processing conditions, material surface and bulk properties. A wide band microphone is used to record …

Physics and application of an atmospheric pressure plasma jet
… In this work we present the use of Thomson scattering to measure the spatially resolved properties of the electrons in a kHz-driven helium APPJet. Since the jet propagates into air, a key aspect of this approach is to distinguish the three types of laser scattering; Rayleigh, Thomson and …

Multispectral optical depth measurements in post-detonation high explosive fireballs
… which is manufactured by Teledyne RISI. Five laser wavelengths were studied which cover the visible through long-wave infrared region of the spectrum. These 405nm, 532nm, 650nm, 1310nm and 9600nm lasers were used to probe the post-detonation fireballs for the first 5ms after initiation. The …
