Charles Townes, the inventor of the laser, has died at age 99, the University of California at Berkeley has announced.
Born in 1915, in Greenville, South Carolina, Townes first conceived the idea of a short-wavelength, high-frequency beam while sitting at a park bench in Washington DC during the spring of 1951.
With the help of fellow scientists and students James P. Gordon and H. J. Zeiger, Townes was the first to create a device capable of harnessing ammonia molecules to amplify microwave frequencies to around 24.0 gighertz. The device in question was dubbed a maser, which stands for Microwave Amplification by Stimulated Emission of Radiation.
