Published in 2020 at "Journal of Materials Processing Technology"

DOI: 10.1016/j.jmatprotec.2019.116372

Abstract: Abstract Underwater local dry laser welding of TC4 alloy was carried out through a double-side gas-shielding nozzle, and the heat input and defocus distance were optimized by analysing the weld quality. With increasing heat input,… read more here.

Published in 2025 at "Applied optics"

DOI: 10.1364/ao.554833

Abstract: To investigate liquid resistance in underwater laser propulsion, we conducted underwater propulsion experiments with cylindrical titanium targets of identical mass but varying propulsion areas through high-speed photography. An analytical formula was derived to elucidate the… read more here.

Published in 2025 at "Journal of Marine Science and Engineering"

DOI: 10.3390/jmse13122217

Abstract: Underwater laser range-gated imaging (ULRGI) effectively suppresses backscatter from water bodies through a time-gated photon capture mechanism, significantly extending underwater detection ranges compared to conventional imaging techniques. However, as imaging distance increases, rapid laser power… read more here.
