Role of Dissolved Gas in Optical Breakdown of Water: Differences between Effects Due to Helium and Other Gases

Bunkin, N; Ninham, Barry; Babenko, Anatoly; Suyazov, N.V.; Sychev, A.V.


It is shown that water contains defects in the form of heterogeneous optical breakdown centers. Long-living complexes composed of gas and liquid molecules may serve as nuclei for such centers. A new technique for removing dissolved gas from water is developed. It is based on a "helium washing" routine. The structure of helium-washed water is very different from that of water containing dissolved atmospheric gas. It is able to withstand higher optical intensities and temperatures of superheating...[Show more]
