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.
