Mani Lal Bhaumik is a physicist whose pioneering work at Northrop Corporate Research Laboratory led to the development of the first efficient excimer laser in 1973. Originally designed for scientific and industrial applications, the technology became the foundation for LASIK and other laser eye surgeries, restoring vision to millions of people worldwide. Bhaumik’s research exemplified the power of fundamental physics to transform medicine, translating advances in laser science into one of the most successful and widely performed medical procedures of the modern era.
