  This study presents experimental observations of single laser-induced
cavitation bubbles collapsing in water with different levels of air saturation.
The average trends of the bubble size reveal a clear yet little dependence of
the energy dissipation at collapse on the water gas content. Similarly, the
observed trend of luminescence energy at collapse varies within the
investigated range of air saturation levels, in agreement with findings in
similar works. We argue that perturbations in bubble shape may amplify with
decreasing air saturation, consequently affecting light emission.
