5 Dry Laser Peening: Ultrashort Pulsed Laser Peening …

amplitudes. Combining high-speed laser welding with DryLP is expected to be a
suitable strategy for replacing other welding processes, resulting in high productivity.
This combination could be applied in various industrial fields, such as the automotive,
rail, aircraft, and space industries.
In addition, DryLP method has a great potential to be applied in various fields
where conventional peening methods cannot be used, as this process can be performed
under ambient conditions without the use of a plasma confinement medium such as
water or transparent materials. For example, a micro device such as Nano- or MicroElectro Mechanical Systems can be peened by ultrashort laser pulses because the
range of the heat-affected zone by the pulses is on the nano- to micrometer scale.
Additionally, this method can be theoretically performed in a vacuum because there
is no significant difference of the shock pressure between driven in a vacuum and in
air, allowing this method to be used in space.
