Abstract
The fundamental, frequency-doubled and quadrupled wavelengths from a Q-switched Nd:YAG laser were used to produce plasma in an aerosol spray under one-atmosphere pressure conditions. 1064, 532, and 266 nm wavelengths were used independently to understand the effect of wavelength on the generation of plasma and the detection of aerosol particles. A constant-output atomizer was used to create aerosol particles of a median diameter of 0.3 μm at a constant generation rate of 2×106 particles/cm3. The optical emissions from Hg and Cr were recorded using an intensified charge-coupled detector (ICCD) coupled with a 50-cm spectrograph. Temporal information was obtained by delaying and gating the detector after the laser plasma was created in the probe volume.
