Cavitation Bubble Evidence in BA-LIFT Processes

Blister-Actuated Laser-Induced Forward Transfer (BA-LIFT) is a modified LIFT process to avoid the direct interaction between the laser pulse and the transference fluid. In a previous study, the comparison between process images and simulation suggested the existence of a mechanically induced cavitation bubble. In this work, new images have been acquired to evaluate its appearance due to the depressurization of the fluid in the front of the polyimide blister.
