The system in our lab that enables extremely high rate change of materials is called Laser Induced Particle Impact Test (LIPIT). Projectile of micrometer size is placed on to a laser absorbing polymer and gold coated glass substrate. A IR laser pulse excites micro sized particle to a speed of at most 1km/s, which is achieved through rapid expansion of gold gas.
The ability to fabricate complex structures with characteristic length in the submicron and nanometer range opens a pathway towards creating materials with superior mechanical properties that can be tailored to a particular application. We study the mechanical response of structured materials on various time and length scales.
