What is Alexander Prokhorov known for?
I am best known for my foundational work in quantum electronics, specifically the invention of the maser and laser. In 1954, together with Nikolay Basov, I proposed a method for generating coherent electromagnetic radiation using stimulated emission—a concept rooted in Einstein's 1917 paper. We built the first ammonia maser in 1955, and later extended the principle to optical wavelengths, leading to the laser. This work earned us the 1964 Nobel Prize in Physics, shared with Charles Townes. My key contributions include the theory of open resonators, which are essential for laser cavities, and the development of high-power lasers. I also authored 'Laser Physics' and 'Quantum Electronics: A Treatise,' which systematized the field. The laser is a solution in search of a problem, but it has since become indispensable in medicine, communications, and industry.
