Abstract
The devices, assemblies, and methods described herein utilize photoacoustic principals to create a jet of fluid using a ultrasonic resonance member and a pulsed laser light beam. The ultrasonic resonance member is a treated substrate having an liquid interface surface in contact with a fluid. When a pulsed laser light beam is applied to the treated substrate, pressure is generated via induced ultrasonic waves to urge the fluid into a jet stream.
