Laser-induced incandescence: recent trends and current questions

Applied Physics B, 2006
This paper provides an overview of a workshop focused on fundamental experimental and theoretical aspects of soot measurements by laser-induced incandescence (LII). This workshop was held in Duisburg, Germany in September 2005. The goal of the workshop was to review the current understanding of the technique and identify gaps in this understanding ...

Laser-induced incandescence of GaSb/InGaSb surface layers

Optics & Laser Technology, 2018
Abstract Laser-induced incandescence (LII) of a surface layer of GaSb/InxGa1−xSb/GaSb (x = 0.1) sandwich heterostructure is investigated in the visible spectral region under irradiation by the third harmonic of radiation of a Q-switched YAG:Nd3+ laser. Within the laser-induced hot spot on the irradiated surface, strong granularity of LII is observed.

Laser-induced incandescence: excitation intensity

Applied Optics, 1998
Assumptions of theoretical laser-induced incandescence (LII) models along with possible effects of high-intensity laser light on soot aggregates and the constituent primary particles are discussed in relation to selection of excitation laser fluence.

Laser-induced incandescence applied to droplet combustion

Applied Optics, 1995
Laser-induced incandescence (LII) is ideally suited for obtaining high temporally and spatially resolved measurements of soot volume fraction in transient combustion phenomena. We demonstrate qualitative two-dimensional nonintrusive optical measurements of the soot evolution versus time from single fiber-supported burning fuel droplets of heptane and ...

Laser-induced incandescence applied to metal nanostructures

Applied Optics, 1999
Laser-induced incandescence is both characterized and demonstrated for the measurement of metal nanoparticle concentration. Reported are the results of an initial characterization of the spectral and temporal signature of the laser-induced incandescence as a function of the excitation laser fluence and wavelength.

Laser-Induced Incandescence and Other Particle Diagnostics

2023
Optical Diagnostics for Reacting and Non-Reacting Flows serves both as a launch pad for new students of optical diagnostics seeking a “go to” book, and as a resource for the experienced diagnostician seeking to explore new techniques, or new applications of familiar techniques.

Cavity Ringdown Calibration of Laser-Induced Incandescence

Laser Applications to Chemical, Security and Environmental Analysis, 1998
Laser-induced incandescence (LII), a technique which determines relative soot volume fraction, requires calibration to yield quantitative results. Spatially resolved LII signals from soot within a methane/air diffusion flame are calibrated using cavity ring-down (CRD) which avoids extrapolation required of less sensitive methods in current use.

Environmental application of pulsed laser-induced incandescence

Applied Physics B, 2013
A portable instrument based on two-color laserinduced incandescence (LII) technique has been designed and developed for the detection of carbonaceous particles for environmental applications. The instrument has been calibrated by performing LII measurements at the exhaust of a home-made soot generator.
