ABSTRACT
This chapter highlights fundamentals of the laser-generated nanoparticles (NPs) in liquid phase. The pulsed laser ablation in liquid phase was attempted to be covered from its basics to the advanced topics. Laser groove is a form of pits fabricated after the ablation process started and passing the threshold of melting and solidification limit. The chapter focuses on the ablation as a material response to the pulsed laser irradiation. The laser and material interaction, and laser ablation mechanisms in liquid phase such as nucleation and growth of NPs are provided in the initial portion of the work. The term “colloid” can be explained when considering the size phenomenon of the solute particles in a liquid host as put forward by Scottish Chemist Thomas Graham in 1861. Increasing the laser pulse energy will increase the absorbed and deposited energy by the material, and this energy causes the material to increase temperature to the melting point.
