Nws muaj kev ruaj ntseg hais tias lub ntiaj teb uas peb nyob niaj hnub no yuav ntau npaum li cas yog tsis rau lasers. Laser tshuab no tsuas hais txog 100 xyoo, thiab txawm tias ntau hom industries siv tshuab laser tshuab, Tseem ntau heev nyob rau hauv nws cov infancy.
Li ntawd,, Cas peb tau mus no taw tes uas lub neej tsis lasers nkawd li nws yuav luag tsis yooj yim sua? Wb coj saib tom qab keeb kwm laser tshuab nrhiav.
Albert Einstein pib lub zog laser.
Txoj kev rov qab 1917, Tus poj Albert Einstein luam tawm ib daim ntawv hu ua "Zur Quantentheorie der Strahlung" (uas txhais tau tias "Rau lub Quantum ziag ntawm Radiation") uas pab pw hauv lub foundation rau dab tsi yuav nws thiaj li ua laser tshuab laser. Nyob rau hauv nws daim ntawv, Einstein—leej twg, Peb yuav tsum tau taw tes tawm, Yog inspired los ntawm kev tshawb no ua ntej lawm kawm ua ntej lawm los ntawm Max Planck rau txoj kev sib raug zoo uas tshwm sim ntawm tawg thiab zog—xav paub meej tias ziag no nws muaj nyob rau hauv ib lub tswvyim hu ua "Stimulated Emission." Einstein tus ziag no twb mus ua si ib pivotal lub luag hauj lwm pivotal hauv laser tshuab mus rau pem hauv ntej.
Xav laser innovations.
Thaum Einstein nteg lub groundwork rau dab laser tshuab yuav nws thiaj li ua, Nws tsis ua si ib qho loj nyob rau hauv txoj kev loj hlob ntawm nws. Tiag Mas, lwm zaum uas khaws qhov twg Einstein tshuav thiab ua hauj lwm los ua pov thawj nws ziag thaum thawb nws rau pem hauv ntej. Ib tug zaum zoo li no Rudolf Ladenburg, leej twg paub tseeb hais tias tus Einstein yeej tseem nyob hauv lub caij 1920s. Lwm tus paub txog yog Valentin Fabrikant, leej twg muab Einstein txoj kev tshawb xav thiab ua raws li nws los ntawm theorizing uas stimulated emission yuav siv los amplify tawg.
Tus 1950s tau ib txoj siav kis.
Thoob plaws hauv lub 1920s, 1930s, thiab 1940s, Tshuab laser tshuab yog tseem, Ntau los tsawg me ntsis, Kev tshawb xav tias zaum tau sim tawm hauv pem teb. Tab sis thaum lub 1950s kuav los tiag nyob ib ncig ntawm, Tshuab laser technology tsiv mus nyob rau theem tom ntej, vim loj rau qhov tireless ua hauj lwm ua los ntawm zaum xws li Charles Townes, Alexander Prokhorov, thiab Nikolay Basov. Lawv ua haujlwm los tsim cov kev tshawb xav txog stimulated emission thiab, ntxhov siab, Lawv tau zoo nyob rau hauv demonstrating lub emission stimulated ntawm microwaves. Lawv twb tuaj winning tus nqi zog Nobel nqi zog rau qhov tseem ceeb ua hauj lwm uas lawv tau ua.
Txawm li cas los, Nws tsis yog kom txog thaum lub caij 1950s tias lub tswvyim ntawm lub tswvyim sib "laser" thaum kawg muab tshem tawm. Gordon Gould, ces ib Columbia University kawm tiav, tus emission stimulated emission yuav tau utilized rau amplify teeb. Nws yog tus thawj zaug zaum npib rau lub sij hawm "laser,"Uas yog ib qho acronym rau "Teeb Amplification los ntawm Stimulated Emission of Radiation."
Nws muab daim ntawv lub cev.
Tus 1950s yuav tau muab lub npe. Tab sis nws muab kom txog rau thaum 1960 Rau tus thawj heev laser coj zoo lawm. American physicist Theodore Maiman yog muab rho uas muab tus thawj laser ua ke ntawm Hughes Research Laboratories hauv Malibu, California. Tus laser uas Maiman ua relied rau synthetic ruby xa tawm ib beam ntawm lub teeb. Lub teeb muaj ib wavelength 694.3 naj npawb.
Nws evolved sai los muaj.
Thaum Maiman tsim cov ruby laser, Muaj ob peb lwm lasers uas raws li. Nyob rau hauv 1960, Roj laser tau invented los physicist Ali Javan. Nyob rau hauv 1962, ib semiconductor txhaj laser yog tsim los ntawm inventor Robert cuab. Thiab nyob rau hauv thiab nyob rau hauv 1964, Ib cov dioxide laser yog founded los ntawm engineeral Kumar Patel. Cov pa roj carbon dioxide laser, ua particular, Ua ib tug txaws loj nyob hauv lub ntiaj teb vim nws yog cheaper dua cov ruby laser thiab kuj ntau npaum li cas. Nws tseem yog tus nyiam tuaj laser rau lub ntiaj chaw hnub no.
Laser Technology tseem hloov qhov uas peb yeej nyob.
Laser Technology tseem hloov qhov uas peb yeej nyob.Txij thaum lub 1960s, Tshuab laser tau txuas mus evolve thiab hloov lub neej ntawm txhua thoob ntiaj teb. Nyob rau hauv cov 1970s, Zaum pom muaj ib txoj kev siv lasers los etch silicon computer. Nyob rau hauv cov 1980s, Lawv siv lawv kom laser qhov muag phais ib tug tseem. Thiab puas txij thaum ntawd los, Tshuab laser tau cia rau kev loj hlob. Nws yuav nyiam saib npaum li cas ntxiv ntiaj teb yuav thawb nws dua lwm 100 xyoo.
Nyob Seiffert muaj, tshwj xeeb muab tuam txhab uas muag nrog laser alignment lub nruab thiab raws li lwm cov cuab yeej cuab tam uas pab kom lawv khaws lawv tej khoom thiab khiav. Yog hais tias koj xav kawm seb koj lub tuam txhab yuav tau kev pab los ntawm utilizing lassers, hu rau peb 800-856-0129 Hnub no.
