CHARLES H. TOWNES
The physicist dated and signs a 6x4 florescent yellow card
Signature: "Chas. H. Townes/April 27, 2012". 6x4 card. American physicist Charles HardTownes (1915-2015), shared the 1964 Nobel Prize for Physics with Soviet scientists Aleksandr M. Prokhorov and Nikolay G. Basov "for fundamental work in the field of quantum electronics, which has led to the construction of oscillators and amplifiers based on the maser-laser principle". Townes created the first maser - a predecessor to the laser that amplified microwaves - with two students in 1953. He and A. L. Schawlow also showed that it was possible to construct a laser in 1958, two years before the first ruby laser was built by Theodore Maiman. Fine condition.
