Abstract
A process of forward deposition of a material onto a target substrate is accomplished by passing a burst of ultrafast laser pulses of a laser beam through a carrier substrate that is transparent to a laser beam. The carrier substrate is coated with a material to be transferred on the bottom side thereof. Electrons on the back side of said transparent carrier coated with the material are excited by the first few sub-pulses of the laser beam which lifts the material from the carrier substrate and subsequent sub-pulse of the laser beam send the material into space at hypersonic speed by a shock wave that drives the material with forward momentum across a narrow gap between the carrier substrate and the target substrate, and onto the target substrate.
