description Alexander Prokhorov Overview

Alexander Prokhorov was a pioneering Soviet physicist instrumental in the development of stimulated emission, the fundamental principle behind lasers and masers. His experimental work during World War II led to the creation of the first working device, paving the way for significant advancements in telecommunications, medicine, and materials science. Prokhorov’s research earned him a share of the 1964 Nobel Prize in Physics recognizing his groundbreaking contributions to quantum electronics. He is primarily relevant to scientists, engineers, and researchers involved in optics, photonics, and related fields.

help Alexander Prokhorov FAQ

What did Alexander Prokhorov win the Nobel Prize for?

Prokhorov shared the 1964 Nobel Prize in Physics with Nikolai Basov and Charles Townes for fundamental work in quantum electronics that led to the construction of masers and lasers. The three researchers independently established the principles of stimulated emission of radiation at microwave and optical frequencies.

Where did Alexander Prokhorov conduct his research?

Prokhorov spent the majority of his career at the P. N. Lebedev Physical Institute of the Soviet Academy of Sciences in Moscow. He and Basov developed their maser concepts while working together at Lebedev in the early 1950s, using molecular beams as the active medium.

What was Prokhorov's specific contribution to laser science?

In 1958, Prokhorov and Basov published a proposal for using a Fabry-Pérot resonator (parallel mirrors) as an optical cavity for lasers, a concept developed independently by Townes and Schawlow in the United States. This resonator design became fundamental to the practical construction of laser devices.

Was Alexander Prokhorov involved in any other scientific organizations?

Prokhorov served as editor-in-chief of the Great Soviet Encyclopedia for many years and was a prominent figure in the Soviet scientific establishment. He also helped establish the General Physics Institute in Moscow, which was later named in his honor.
