A bubble that collapses near a rigid boundary develops a liquid jet. The jet shoots through the bubble in direction towards the boundary. When it hits the bubble wall a sequence of shock waves is emitted that is followed by the onset of a structure moving in opposite direction to the jet. This structure is called counterjet. In this paper we experimentally investigate the onset of the counterjet, the evolution of its height, the duration of its appearance and its consistence. Bubbles are induced by means of a strong laser pulse and observed with high-speed cinematography.
