Abstract

KORNEEV, N. et al. Thermoactivated cavitation induced in water by low power, continuous wave thulium-doped fiber laser. Rev. mex. fis. [online]. 2019, vol.65, n.2, pp.185-189.  Epub Apr 17, 2020. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.65.185.

We demonstrate that by focusing in pure water the light of a CW thulium doped fiber laser tuned at a wavelength close to the 1950 nm absorption line of the water and with power of few hundreds of milliwatts, a thermoactivated cavitation bubble formation is obtained. On collapse, a strong ultrasound wave is observed. This effect can be potentially useful for biomedical applications.
