Abstract

An approach is considered that makes it possible to quickly estimate the concentration of various nanoimpurities, including nanobubbles, in water even in samples of small volumes. The method is based on the effect of periodic generation and cavitation collapse of bubbles near the fiber tip during laser heating. We used a laser source with a wavelength of 1.94 μm coupled to an optical fiber with a fiber core diameter of 400 μm. The high sensitivity of the proposed approach lies in the fact that one critical nucleus of a new phase is sufficient for explosive boiling to begin, resulting in a growing bubble.
