...work in the development of the solid state maser--a super high fidelity amplifier of tremendous importance in radio astronomy and satellite communication systems--Nicolaas Bloembergen, Gordon McKay Professor of Applied Physics, will receive the Ballantine Medal of the Franklin Institute at the Institute's annual Medal Day award ceremony tonight...
Bloembergen's maser is used to amplify weak radiations of very short wavelength--for example, microwave radio signals. In use for a year-and-a-half on the Harvard College Observatory's 60-foot radio telescope, the maser has already helped double the known number of radio stars...
Bloembergen conceived the first practical solid state maser in 1956. The first operational version was completed in December, 1956 by a Bell Telephone scientist...
...Masers amplify by way of a special effect of quantum physics known as "stimulated emission of radiation." (The name "maser" stands for "Microwave Amplification by Stimulated Emission of Radiation...
...park bench and pondered a problem in physics: how to produce microwaves shorter than any that had previously been generated. Before he got to breakfast, Townes thought he had the answer?and four years later he completed a device that proved he was correct. It was a maser, in which hopped-up ammonia molecules were made to serve as an atomic clock of unequaled accuracy. Since then, Townes's maser has been used to check Einstein's theory of relativity. It may soon revolutionize radar and open up new channels for communication. Townes is currently on leave from Columbia University...
