13 de mar. de 2018 · The Man, the Myth, the Laser. The disputed origin story of one of the 20th century’s most important inventions. They’re at the grocery checkout. They kill cancer cells. They’re in pointers that drive cats crazy and in the fiber networks that connect us to the internet.
The invention of the maser (microwave amplification of stimulated emission of radiation) in 1954 by Charles Townes and Arthur Shawlow led to new investigations into light amplification by stimulated emissions of radiation, or laser, a term coined by American physicist Gordon Gould in 1957.
No ano de 1960 o físico Theodore Harold Maiman (11 de julho de 1927 - 5 de maio de 2007) inventou um aparelho que emite um tipo de luz especial: o raio laser (lê-se "lêiser"). Esse nome vem das iniciais da expressão inglesa Light Amplification by Stimulated Emission of Radiation, traduzindo para a língua portuguesa, lê-se "amplificação ...
16 de mai. de 2019 · Moon-measurer, laser inventor remembered at International Day of Light. When NASA scientists wanted to measure the distance from Earth to the moon for the first time, they shone a high-powered laser off of a reflecting disk placed on the moon by the astronauts during the 1969 Apollo 11 mission.
