Aleksandr Mikhaylovich Prokhorov didn’t just study light. He helped teach it how to behave.
Born in Australia in 1916, he spent his early years in exile. His father, a revolutionary, had fled the Russian Empire. The family settled in Atherton, Queensland. Then came the Russian Revolution. In 1923, they returned to the homeland. Prokhorov grew up in a country tearing itself apart and rebuilding. He ended up in Moscow. He ended up changing physics.
Prokhorov died in 2002. But his work remains in the barcode scanners at grocery stores, the fiber-optic cables carrying your internet data, and the surgical tools that can cut tissue without bleeding.
How the Maser and Laser Were Born
The story of the laser starts with a gap. A gap in knowledge. A gap between what was possible and what was real.
In 1952, Prokhorov and his colleague Nikolay Basov were at the P.N. Lebedev Physical Institute. They were looking at quantum electronics. Specifically, they were looking at how atoms interact with electromagnetic waves.
They came up with a radical idea. They suggested a method to amplify these waves. Not just any waves. Parallel ones. Waves that were all in phase. All the same wavelength.
This was the theoretical foundation for the maser.
By the time Prokhorov and Basov published their findings in 1954, Charles Townes in the United States had already built the first working maser. Townes had beaten them to the hardware. Prokhorov and Basov had beaten him to the theory? Maybe. Or maybe they were just thinking in parallel. Independent discovery is a messy thing in science.
The principle was simple in concept but devilish in practice. Stimulated emission. You get an atom to release a photon. That photon hits another excited atom. That atom releases a twin photon. Now you have two. Hit another. Four. Eight. A cascade. A coherent beam of light.
From Theory to Sharp Tool
Prokhorov didn’t stop at theory. He became head of the Oscillation Laboratory in 1954. He later became a professor at Moscow State University. He wrote extensively on infrared and visible-light lasers.
He understood that the maser was just the beginning. The next step was shrinking the wavelength. Moving from microwaves to infrared. Then to visible light.
This shift mattered. Microwaves are great for radar. Visible light is great for cutting, welding, reading data, and talking to satellites.
Prokhorov’s work on nonlinear optics was foundational. It explained how light interacts with matter when the intensity is high. It explained why the medium itself changes when the light hits it.
In 1964, the Nobel Committee recognized this. Prokhorov shared the prize with Basov and Townes. It was for fundamental research in quantum electronics. For the development of the maser and laser.
He received the Lenin Prize in 1959. Two Orders of Lenin. Medals. He served as editor-in-chief of the Great Soviet Encyclopedia from 1969 to 1978. These are
