Probing the Dissolved Gas Concentration on the Electrode through Laser-Assisted Bubbles

We demonstrate that the irradiation of a single laser pulse onto the electrode assists the formation of bubbles, and this phenomenon can be conveniently used to probe the dissolved gas concentration on the electrode. The obtained concentrations agree well with the values inferred through linear extrapolation of gas concentration in proximity to the electrode to the electrode surface.

Automated summary

The irradiation of a single laser pulse onto the electrode assists the formation of bubbles, which can be used to probe the dissolved gas concentration on the electrode. The obtained concentrations agree well with inferred values through linear extrapolation of gas concentration in proximity to the electrode to the electrode surface.
