Mr. Charles Towns was born on July 28, 1915 on the farm of the Green Building in South Carolina, USA. localFurman UniversityHe became fascinated by physics and natural sciences, graduated with a chief university at the age of 19 in 1935. Mr. Town who later got a doctorate in physics, until 1947Bell LaboratoriesI worked at. During the Second World War he was involved in designing a radar bombing system and began research on laser generation from 1950.


One day in 1951, when Mr. Towns, who was 35 years old, was sitting on a bench in a park in Washington, suddenly "generating a beam with short wavelength and high frequency light", a solution to the problems that we have addressed for many years He told me he came up with. In 1954, Towns et al. Succeeded in generating and amplifying microwaves by stimulated emission, using a device using ammonia gas. Taking acronym for "microwave amplification by stimulated emission of radiation", "Maser"It was named.

In 1958, along with Arthur Shawlow of Nobel laureate and brother-in-law, I proposed an idea to visualize maser. This is the "laser"In 1959, at the National Defense Analysis Institute in 1959, I succeeded for the first time in demonstration" Open Door with Laser ". Thanks to these achievements, Mr. Towns ·Alexandre ProkhorovMr·Nikolay · BassofThree of Mr. was awarded the Nobel Prize in Physics in 1964.


Currently, lasers are used for various products such as home appliances, optical fibers, surveying instruments, printers, entertainment show lights and laser pointers. Mr. Town himself continued his research applying maser to radio astronomy and developed "infrared space interferometer" which is the world's first astronomical interferometer to observe the mid infrared region by laser,Interstellar matterAnd we measured the mass of the black hole in the center of the galaxy for the first time.

Mr. Towns, who retained a brilliant achievement, has been recognized as a member of the National Academy of Sciences, National Inventors Hall of Fame, has received an honorary degree from 25 universities, and received science honor prizes etc. from various places etc. We have won various awards. A wife who got married in 1941 has four daughters, six grandchildren and two grandchildren are also born. He was visiting the office on campus and the Institute of Space and Astronautical Science, as an emeritus professor at the University of California, Berkeley, until the deceased year before 2014.

Advances in lasers are still continuing, and in ChinaSystem that intercepts drones with laserIt is under construction. Also, a movie that has successfully captured the locus of the laser beam for the first time with 20 billion high-speed cameras per second has also been released.
