Abstract

Disclosed is a system including a substrate having a first side and a second side and a layer of photoacoustic material disposed on the first side of the substrate. The layer of photoacoustic material is configured to generate a directional ultrasound wave in response to a laser beam impinging on the layer. A conduit may be coupled to the housing and have an opening adjacent to the layer of photoacoustic material; the directional ultrasound wave may be directed through fluid that is contained in the conduct to generate a liquid jet in a liquid.
