Pulsed laser ablation has a wide array of applications in the materials science processing of today. This thesis focuses on the use of pulsed laser ablation to i) process ceramic materials to introduce hydrophobic properties to their surfaces for use in lunar dust adhesion mitigation and ii) synthesize Ag nanoparticles for use in antibacterial applications. The laser processing parameters for the formation of hydrophobic surfaces in B4C and MoAlB ceramics were determined experimentally, and the efficacy of lunar dust adhesion mitigation was investigated. The properties of the laser synthesized Ag nanoparticles were characterized, and they were later used in antibacterial assays.
