• Comparisons of light emissions from multibubble and single-bubble sonoluminescence in the near-infrared band extending from 800 to 1050 nm have been investigated. In argon-water mixtures, single-bubble and multibubble spectra are similar in appearance. In sodium chloride-water mixtures, the multibubble spectrum shows evidence of the 3d-3p sodium emission line, whereas the single-bubble spectrum shows no such emission. For single bubbles, the near-infrared emissions change linearly with driving pressure. No evidence of near-infrared emissions are observed below the visible luminescence threshold.
