Abstract
The present disclosure relates to a novel continuous laser nanoforming device, and the methods to make and use the continuous laser nanoforming device.
Claims20
A continuous laser nanoforming device, comprising:
- a nanomold configured to continuously receive and transport a metallic film, wherein the metallic film includes a metal layer and an ablative layer;
- a laser generator configured to generate a laser beam to hit the ablative layer of the metallic film to generate a shockwave and thereby create a nanoformed metal from the metallic film as the metallic film moves relative to the laser generator;
- and
- a confinement layer configured to confine the shockwave during continuous motion of the metallic film relative to the confinement layer and the laser generator, wherein the confinement layer is configured to contact the ablative layer to press the metallic film against the nanomold while the metallic film moves relative to the confinement layer and the laser generator such that the confinement layer is disposed between the laser generator and the metallic film, and the laser beam is transferred through the confinement layer toward the ablative layer of the metallic film.

A laser nanoforming device, comprising:
- a nanomold configured to continuously receive and transport a multilayer film, wherein the multilayer film includes a metal layer and an ablative layer;
- a first laser generator configured to direct a first laser beam onto the ablative layer of the multilayer film as the multilayer film moves relative to the first laser generator to produce a nanoformed material when the first laser beam generates a shockwave at a surface of the multilayer film;
- a confinement material disposed between the first laser generator and the multilayer film, wherein the confinement material is configured to press the multilayer film against the nanomold while the first laser beam is transferred through the confinement material toward the ablative layer such that the confinement material is configured to confine at least a portion of the shockwave during continuous motion of the multilayer film relative to the confinement material and the first laser generator;
- a rotary film feeder configured to join the nanoformed material with a substrate material;
- and
- a second laser generator configured to weld the nanoformed material to the substrate material.

A laser nanoforming device, comprising:
- a rotary nanomold configured to continuously receive and transport a multilayer film, wherein the multilayer film includes a metal layer and an ablative layer;
- a laser generator configured to direct a laser beam onto the ablative layer of the multilayer film as the multilayer film moves relative to the laser generator to generate a shockwave and thereby produce a nanoformed material;
- a transparent confinement material disposed between the laser generator and the multilayer film, wherein the transparent confinement material is configured to transfer the laser beam therethrough toward the ablative layer during continuous motion of the multilayer film relative to the transparent confinement material and the laser generator;
- and
- a back support positioned adjacent to the transparent confinement material;
- wherein the rotary nanomold and multilayer film are configured to translate between the transparent confinement material and the back support, and
- wherein the transparent confinement material is configured to press the multilayer film and the rotary nanomold against the back support as the layer multilayer film and rotary nanomold translate relative to the transparent confinement material and the back support.
