It's funny to consider that in 1958 when American researcher Charles Townes showed that a MASER could theoretically become to function in the visible region of spectrum.
However, colleagues told him "that his work would have little relevance to the real world". In 1958, the "hula hoops" were all the craze across Europe and Russian writer Boris Pasternek declined the Nobel Prize in Literature due to the fact that he feared the authorities would ***e him from Russia.
It is likely that the world was drastically changed by the time Charles Townes received the Nobel Prize in Physics four years later. Nowadays, lasers are employed in all aspects of life including a ever increasing number of cosmetic treatments, including treatment of wrinkles and acne scars, the ***al of tattoos, hair ***al as well as pigmented blemishes (age moles and spots) as well as the treatment of vascular lesions (port staining of wine and spider veins).In truth, the story of lasers began many years before.
In the year of 1917, the renowned physicist, Albert Einstein postulated that atoms could be induced to emit tiny particles of energy referred to as "photons," in his treatise "On the Theory of Quantum Radiation." This sentinel piece of physics established the foundations for the theory of stimulated radiation emission, which was later used by the by American physicist, Gordon Gould to coin the acronym LASER.
In essence, the term is an abbreviation of the term light ampli***ation through stimulation of emission radiation.The time was in 1957 and that was the year when the Russians were just about to launch Sputnik 1 into the skies over the astonished US nation. The Senator Lyndon Johnson spoke for the nation when he said "soon they'll be dropping bombs at us from space, like children dropping rocks on cars via the freeway crossings!".
Newspaper headlines of the day expressed his concern when one of them stated that "Soviet satellites circle the globe every one hour". In 1960, plans were made to start the space race , and America inaugurated a brand new age of political, technological, military, and scienti*** advances.
The Government formed the Department of Defense's Defense Advanced Research Projects Agency and m***ve grants were poured into the public and private laboratories throughout the United States to fund the creation of a new spacecraft as well as the first operational laser.In 1960, their efforts paid off as physicist Theodore Maiman working with the Hughes Electric Corporation in California invented the world's first functioning Ruby laser.
