Plasmonics, the study of the interaction between electromagnetic fields and free electrons in metal nanostructures, has emerged as a promising field with diverse applications in photonics and laser optics. Plasmonic structures exhibit unique optical properties, such as localized surface plasmon resonance and enhanced electromagnetic field confinement, which can be harnessed for a wide range of applications in next-generation laser optics. This article provides an overview of the recent advancements and applications of plasmonics in laser optics, highlighting their potential to revolutionize various aspects of laser technology. Plasmonic nanostructures, such as metallic nanoparticles, nanowires, and nanoantennas, offer versatile platforms for manipulating light at the nanoscale. These structures can confine light into sub wavelength volumes, leading to enhanced light-matter interactions and enabling applications such as surface-enhanced Raman spectroscopy nonlinear optics, and optical sensing. By engineering the size, shape, and composition of plasmon nano structures, researchers can tailor their optical properties to meet specific application requirements in laser optics.
