Journal ArticleDOI
Development of a deep-sea laser-induced breakdown spectrometer for in situ multi-element chemical analysis
Blair Thornton,Tomoko Takahashi,Takumi Sato,Tetsuo Sakka,Ayaka Tamura,Ayumu Matsumoto,Tatsuo Nozaki,Toshihiko Ohki,Koichi Ohki +8 more
TL;DR: In this article, a deep-sea laser-induced breakdown spectrometer (ChemiCam) was deployed to perform in situ multi-element analysis of both seawater and mineral deposits at depths of over 1000m.
Journal ArticleDOI
Simultaneous observation of nascent plasma and bubble induced by laser ablation in water with various pulse durations
TL;DR: In this paper, the effects of pulse duration on the dynamics of the nascent plasma and bubble induced by laser ablation in water were investigated, and it was shown that the extent of the plasma quenching in the initial stage significantly depends on the pulse duration.
Journal ArticleDOI
Effects of pulse width on nascent laser-induced bubbles for underwater laser-induced breakdown spectroscopy
TL;DR: In this article, shadowgraphs of nascent cavitation bubbles generated by pulsed laser irradiation of Cu targets in water were observed for two different pulse widths, 20 ns and 150 ns.
Journal ArticleDOI
On-Site Quantitative Elemental Analysis of Metal Ions in Aqueous Solutions by Underwater Laser-Induced Breakdown Spectroscopy Combined with Electrodeposition under Controlled Potential
Ayumu Matsumoto,Ayaka Tamura,Ryo Koda,Kazuhiro Fukami,Yukio H. Ogata,Naoya Nishi,Blair Thornton,Tetsuo Sakka +7 more
TL;DR: A technique of on-site quantitative analysis of Zn(2+) in aqueous solution based on the combination of electrodeposition for preconcentration ofZn onto a Cu electrode and successive underwater laser-induced breakdown spectroscopy of the electrode surface under electrochemically controlled potential is proposed.
Journal ArticleDOI
Long-duration nano-second single pulse lasers for observation of spectra from bulk liquids at high hydrostatic pressures
TL;DR: In this article, the influence of laser pulse duration on the spectral emissions observed from bulk ionic solutions has been investigated for hydrostatic pressures between 0.1 and 30 MPa, with the latter lasting longer for the 150 ns pulse compared to a 20 ns pulse of the same energy.
