| Abstract | The phenomenon of laser-induced incandescence (LII) has been utilized to develop versatile diagnostic techniques for measurements of combustion-generated soot concentration and primary particle size in many combustion applications. Many aspects in the implementation of LII have been investigated, such as the excitation laser wavelength and spatial profile, signal detection timing (prompt or delayed) and temporal width, and signal detection wavelengths. One potentially important parameter in LII practice that has received little attention in the LII community is the laser pulse duration. This is perhaps due to the fact that almost all the LII experiments conducted in the last two decades employed Q-switched, flashlamp pumped Nd:YAG lasers as the light source, which all provide a similar pulse duration in a narrow range between 5 and 10 ns FWHM. Few LII experiments were conducted using a much long laser pulse (microsecond) or much a shorter one (picoseconds). Picosecond laser pulses were shown theoretically to provide advantages over nanosecond ones in the determination of primary particle size distribution using lowfluence LII in flames at elevated pressures. |
