Answer
Prokhorov shared the Nobel Prize in Physics in 1964 with Nikolay Basov and Charles Hard Townes for their research on masers and lasers. The maser is a device that amplifies microwaves using stimulated emission of radiation, and the laser is a device that amplifies light using the same principle. Prokhorov's work on masers and lasers helped to lay the foundation for the development of these important technologies.
