WhoInventedTnwsLaser?
Laser (LA-SER) yog acronym tsim los ntawm qhov pib ntawm lus Askiv Lub Teeb Pom Kev los ntawm Kev Sib Tw Txaus siab ntawm Kev Tsoo Hluav Taws Xob, uas txhais tau tias ua kom nthuav dav los ntawm lub teeb tawm ntawm lub teeb.
Lo lus laser hauv lus Askiv yog muab los ntawm thawj tus ntawv LASER, uas txhais tau tias luv ntawm lo lus Askiv"
Cov ntsiab lus tseem ceeb hauv cov thev naus laus zis thev naus laus zis twb tau tsim los thaum Einstein npaj" nyob rau hauv 1917. Lo lus laser yog ib zaug kev tsis sib haum; Gordon Gould yog thawj tus siv los siv cov lus no hauv cov ntawv sau tseg.
Xyoo 1953, American physicist Charles Hud Towns thiab nws tus tub ntxhais kawm Arthur Sholow ua thawj microwave quantum amplifier, uas tau txais cov ncauj lus me me.
Xyoo 1958, CH Towns thiab AL Qhia Qes tau txuas ntxiv lub hauv paus ntsiab lus ntawm microwave quantum amplifier mus rau qhov kho qhov muag tau.
Xyoo 1960, TH Theodore Mayman ua thawj lub ruby laser.
Xyoo 1961, Iranian tus kws tshawb fawb A. Jia Wen thiab lwm tus ua ib lub helium-neon laser.
Xyoo 1962, RN Hall thiab lwm tus tsim cov gallium arsenide semiconductor laser.
Hauv xyoo 2013, cov kws tshawb nrhiav ntawm National Laser Center ntawm South African Scientific thiab Industrial Research Council tau tsim lub ntiaj teb thawj zaug digital laser, qhib kev cia siab tshiab rau cov ntawv thov laser. Cov kev tshawb fawb pom tau muab tshaj tawm nyob rau hauv British" Qhov Kev Sib Txuas Lus GG; magazine rau Lub Yim Hli 2, 2013.
Cov hom thiab kev siv cov lasers
Qhov zoo ntawm lub teeb tawm ntawm lub laser yog ntshiab thiab lub teeb pom kev ruaj khov, tuaj yeem thov ntau txoj hauv kev.
Ruby laser: lub laser qub tau ruby zoo siab los ntawm lub teeb ci ci, thiab cov laser ua tau yog" pulse laser" hloov qhov nruam thiab ruaj khov nqaj. Qhov ua tau zoo ntawm cov nqaj tsim los ntawm hom laser no yog qhov tseem ceeb txawv ntawm cov laser uas ua los ntawm lub laser diode uas peb siv. Qhov no khaus lub teeb tawm ntev tsuas yog siv ob peb nanoseconds zoo heev rau kev ntes cov khoom txav tau yooj yim, xws li tua holographic portraits. Tus thawj lub teeb duab laser tau yug xyoo 1967. Ruby lasers yuav tsum rubies kim thiab tsuas tuaj yeem tsim cov teeb pom kev luv luv.
HeNe laser: Xyoo 1960, cov kws tshawb fawb Ali Javan, William R. Brennet Jr. thiab Donald Herriot tsim qauv HeNe laser. Nov yog thawj cov roj laser. Cov laser no feem ntau siv los ntawm kev thaij duab holographic. Ob qhov zoo: 1. Ua haujlwm txuas ntxiv laser tsim tawm; 2. Tsis xav tau qhov muag teeb lub teeb rau lub teeb pom kev zoo, thiab siv hluav taws xob los txhawb nqa roj.
Laser diode: Laser diode yog ib qho ntawm feem ntau siv cov lasers. Qhov tshwm sim ntawm qhov tshwm sim txig ntawm hluav taws xob thiab qhov ntawm ob sab ntawm diode' s PN kev sib tshuam yog hu ua nthawv hluav taws xob. Thaum cov tshuab hluav taws xob tsim los ntawm hluav taws xob kis tau los ntawm lub tshuab hluav taws xob, thaum lawv dhau qhov chaw ze ntawm lub tshuab hluav taws xob-qhov hluav taws xob, lawv tuaj yeem muaj siab rau recombine thiab tsim cov duab tshiab. Cov yees duab no tau tsim muaj cov neeg nqa khoom zoo txaus ntshai rau recombine thiab emit tshiab photons. Qhov tshwm sim no yog hu ua kev tawg hluav taws xob. Yog tias qhov kev txhaj tshuaj tam sim no loj txaus, ib tus neeg nqa khoom tau xa tawm ncaj qha rau hauv lub xeev qhov sib luag ntawm cov cua sov yuav raug tsim, uas yog, cov lej ntawm cov khoom seem yuav thim rov qab. Thaum cov neeg nqa khoom hauv cov txheej txheej nquag raug thim rov qab ntau, qhov nyiaj me me ntawm photons uas tsim los ntawm hluav taws xob kis tau los yuav tsim hluav taws xob vim muaj kev cuam tshuam ntawm ob qho kawg ntawm cov kab rov ua kom rov zoo, uas ua rau muaj kev cuam tshuam zoo ntawm kev xaiv ntau zaus, lossis qhov nce ntawm ib qho zaus. Thaum qhov nce ntau dua li qhov nqus poob, coherent teeb nrog zoo spectral kab-laser tuaj yeem tawm los ntawm PN kev sib tshuam. Kev tsim ntawm laser diodes tau ua kom qhov kev xa tawm sai ntawm cov ntawv thov laser. Cov ntaub ntawv sib txawv ntawm cov ntaub ntawv, kev sib txuas lus fiber ntau, laser thaj tsam, laser radar, cov ntaub ntawv laser, laser taw tes, lub khw muag khoom, thiab lwm yam, tab tom tsim kho thiab muaj koob npe.
