Show Laser Laser All All Together To ether The laser craze now sweeping the country's scientific circles was little more than science fiction a decade ago TODAY THE laser performs Its magic tricks in Industrial plants com communications centers and college campuses such as the University of Utah University of Utah physics professor Dr Grant R. R Fowles who In the past five years has I received more than in grants to study the Ingenious light amplifying device de describes describes describes de- de scribes the laser as a machine which gets atoms to cooperate with each other so that they emit light coherently IN A NORMAL source of light such as an incandescent light bulb atoms emitting light dont don't know what their fellow atoms are doing he explained The laser disciplines the atoms forcing the them m to cooperate with each other or to cohere The result Is a intensity high-intensity monochromatic monochromatic monochromatic mono mono- chromatic beam of light The Utah physicist compares the transformation of light in a laser to hand clapping SCATTERED applause at a concert is muffled sometimes hardly audible but syncopated clapping chapping at a rock and roll session session session ses ses- sion is so intense that the effect can be at almost most deafening he says I The laser principle of light amplification was adapted from the mazer or radio wave amplifier amplifier amplifier fier theoretically suggested by Nobel Prize winner Charles Townes in then scientists have been using the laser as a research tool to find out more about light and the Interaction interaction interaction inter Inter- action of light with matter SCIENTISTS Industrialists communications experts and doctors have quickly realized the merits of the highly complex device Laser beams are used in Industry in industry industry in- in for micro w welding micro e 1 d i n g micro drilling and cutting In communications B Bell e 11 Telephone Telephone Telephone Tele Tele- phone has undertaken a multimillion multimillion multimillion multi- multi million dollar laser research project hoping that ev eventually a single laser beam will be able to transport millions of telephone telephone telephone tele tele- phone conversations PERHAPS THE biggest single market for laser exploitation Is the field of medicine where the possibilities for major breakthroughs breakthroughs breakthroughs break break- are Infinite The laser had already been employed ef effectively effectively ef- ef in eye surgery as a welding torch to mend detached retinas Lasers range in price from lowest price gas laser to power high-power ruby laser I DR FOWLES FOWLE'S research at atthe atthe atthe the University of Utah includes development of the worlds world's first visible iodine laser beam His research for new substances substances substances sub sub- stances has also lead to the us of the metal vapors of lead zinc and tin tin another another first This discovery Is important because metal vapors have ex extremely extremely ex- ex high amp amplification c a on compared with other substances substances substances sub sub- stances says the Utah |
