WebSep 4, 2024 · Particular to laser-induced plasma, ... Spectra were collected following laser-induced breakdown initiated in ambient laboratory air using a Quantel Ultra Light Q-switched Nd:YAG laser with a pulse width of 8.5 ns, as measured by a fast silicon photodiode. The laser operated at the fundamental wavelength of 1064 nm with an average energy per ... WebFeb 25, 2015 · The spatial and temporal evolution of plasma generated via laser-induced breakdown in air was investigated. The plasma was produced in air using a focused Nd:YAG Q-switched laser (λ = 1064nm; pulse duration >5ns; pulse energy >60mJ). The interference patterns of the resulting plasma were measured as a function of time using a Nomarski ... lighting brownsville texas

This is important in the … WebNov 27, 2024 · The behaviour of laser-induced plasma in air is first investigated and analysed. The laser-induced plasma image velocimetry (LIPIV) technique is then evaluated and optimized in quiescent air, so that the uncertainties can be quantified. The influences of the delay time between recorded plasma images and processing methods are evaluated. peak body washington
