Factors Affecting the Random Laser Generation: A Review

ABSTRACT Random lasers, an intriguing branch of photonics research, function distinctively by leveraging disarray and multiple scattering within the gain medium to generate laser emission. While these unconventional lasers offer potential advantages such as low-cost fabrication, wide spectral bandwidth, and resistance to external perturbations, realizing optimal performance necessitates a comprehensive understanding of factors contributing to their generation. This research aims to critically analyze and evaluate these factors through an extensive review of existing literature. The study primarily focuses on material properties, structural characteristics, optical pumping techniques, and environmental factors that influence random laser generation. Our systematic analysis will not only enrich the current understanding of random laser functioning but also offer valuable insights for designing and optimizing these lasers for various applications, including imaging, sensing, and communication
