Status and Development Research of Megawatt-Level Super Power Semiconductor Laser Light Sources
With the continuous expansion of laser application fields and ongoing advancements in the development of ultra-high-power laser sources, megawatt-level semiconductor laser sources have been playing an increasingly important role in driving technological innovation and industry upgrades. Owing to their high-energy density, compactness, and multifunctionality, megawatt-level semiconductor laser sources are gradually becoming core technologies in several key areas. To meet the demand for ultra-high-power laser output, laser beam combining technology is widely used. This technology combines multiple laser beams in a space or frequency, effectively increasing the overall laser output power and overcoming the limitations of single laser sources. Currently, megawatt-level semiconductor laser sources are extensively applied in fields such as defense and military, industrial manufacturing, aerospace, telecommunications, and high-energy physics. In this article, the development status, implementation methods, technical challenges, and applications of megawatt-level semiconductor laser sources are explored, the challenges they face are analyzed, and the vast prospects of megawatt-level laser sources are forecasted.
