Nws yog muaj kev ruaj ntseg hais tias lub ntiaj teb no nyob rau hauv uas peb nyob niaj hnub nim no muaj ntau yam sib txawv yog hais tias tsis rau lasers. Laser technology yog tsuas hais txog 100 xyoo, thiab txawm tias ib tug ntau ntawm cov lag luam siv laser tshuab, nws yog tseem heev npaum li cas nyob rau hauv nws kiag.
Yog li ntawd, yuav ua li cas li cas peb tau mus rau qhov no qhov twg lub neej tsis muaj lasers mas, zoo li nws yuav ua tau yuav luag tsis yooj yim sua? Cia wb mus saib rov qab rau lub keeb kwm ntawm laser tshuab mus nrhiav tau tawm.
Albert Einstein started the laser movement.
Txoj kev rov qab nyob rau hauv 1917, tus poj Albert Einstein luam tawm ib daim ntawv hu ua "Zur Quantum Theory ntawm Tawg" (uas txhais tau tias "Nyob rau hauv Quantum Theory ntawm Tawg") uas pab muab lub hauv paus rau dab tsi yuav nws thiaj li ua laser tshuab. Nyob rau hauv nws daim ntawv, Einstein-uas, peb yuav tsum taw tes tawm, twb tshwm sim los ntawm ib tug ua ntej lawm kev tshawb nrhiav los ntawm Max Planck nyob rau kev sib raug zoo uas tau tshwm sim ntawm tawg thiab lub zog-ntxaws ib ziag no nws nyob rau ib tug tswvyim hu ua "tsa Emission." Einstein tus lub hom phiaj twb tuaj ua si ib pivotal luag hauj lwm nyob rau hauv laser tshuab mus rau pem suab.
Further laser innovations.
Thaum Einstein nteg lub lub hauv paus rau dab tsi laser tshuab yuav nws thiaj li ua, nws tsis ua si ib tug loj ib feem nyob rau hauv txoj kev loj hlob ntawm nws. Es tsis txhob, lwm zaum uas khaws qhov twg Einstein tshuav thiab ua hauj lwm los ua pov thawj nws kev tshawb xav thaum thawb nws rau pem hauv ntej. Ib tug xws li tus paub txog yog Rudolf Ladenburg, uas paub tseeb hais tias Einstein tus thawj lub hom phiaj nyob rau hauv lub lig 1920. Lwm tus paub txog yog Valentin Fabrikant, uas coj Einstein tus lub hom phiaj thiab ua tau raws li nws los ntawm theorizing uas tsa emission yuav siv tau los ua kom nrov loj tawg.
The 1950s were a turning point.
Thoob plaws hauv lub 1920, 1930s, thiab 1940s, laser tshuab yog tseem, ntau dua los yog tsawg, ib ziag ntawd zaum twb ua tau tawm hauv av. Tab sis thaum lub sijhawm xyoo 1950 kuav los tiag nyob ib ncig ntawm, laser tshuab nce mus rau qib tom ntej, vim nyob rau hauv loj ib feem mus rau lub tireless ua hauj lwm ua los zaum zoo li Charles Townes, Alexander Prokhorov, thiab Nikolay Basov. Lawv ua hauj lwm los tsim qhov quantum kev tshawb xav ntawm stimulated emission thiab, tas, lawv twb vam meej nyob rau hauv ua cov tsa emission ntawm microwaves. Lawv twb tuaj winning lub Nobel nqi zog nyob rau hauv Physics rau qhov tseem ceeb ua hauj lwm uas lawv tau ua.
Txawm li cas los, nws tsis yog kom txog thaum lub caij xyoo 1950 uas lub tswvyim ntawm ib tug thiaj li hu ua "laser" thaum kawg coj tawm. Gordon Gould, ces ib tug Columbia University graduate me nyuam kawm ntawv, theorized uas tsa emission yuav tau siv kom nrov loj lub teeb. Nws yog tus thawj tus paub txog rau npib lub sij hawm "laser,"Uas yog ib qho acronym rau" teeb amplification los ntawm tsa Emission ntawm Tawg. "
Nws coj lub cev daim ntawv.
Lub xyoo 1950 tej zaum yuav tau muab lub laser nws lub npe. Tab sis nws coj mus txog rau thaum 1960 rau tus thawj heev laser coj zoo lawm. American physicist Theodore Maiman yog rho nrog muab cov thawj laser ua ke nyob rau Hughes tshawb fawb chaw soj nstuam nyob rau hauv Malibu, California. Lub laser uas Maiman ua tau cia siab rau ntawm cov khoom cua ruby xa tawm ib tug liab beam ntawm lub teeb. Lub teeb muaj ib tug wavelength ntawm 694.3 nm.
Nws hloov zuj zuj sai sai los yeej muaj.
Thaum Maiman tsim lub ruby laser, muaj ob peb lwm yam lasers uas ua raws li. Nyob rau hauv 1960, ib tug roj laser twb yees ua los ntawm physicist Ali Javan. Nyob rau hauv 1962, ib tug semiconductor txhaj laser yog tsim los ntawm inventor Robert Hall. thiab nyob rau hauv 1964, ib tug carbon dioxide laser twb nrhiav tau los ntawm hluav taws xob engineer Kumar Patel. Cov pa roj carbon dioxide laser, nyob rau hauv particular, ua ib tug loj txaws nyob rau hauv lub ntiaj teb no vim hais tias nws yog cheaper npaum li tshaj lub ruby laser thiab kuj yog ib tug ntau ntau. Nws yog tseem nrov tshaj plaws muaj laser ntawm cov ntiaj chaw niaj hnub no.
Laser Technology continues to change the way we all live.
Txij li thaum 1960, laser tshuab tau txuas ntxiv mus rau evolve thiab hloov lub neej ntawm cov neeg nyob ib ncig ntawm lub ntiaj teb no. Nyob rau hauv lub xyoo 1970, zaum pom ib txoj kev siv lasers rau kos silicon computer chips. Nyob rau hauv lub 1980s, lawv siv lawv los ua laser qhov muag phais ib tug ploj. Thiab puas tau txij li thaum ces, laser tshuab tau khaws cia nyob rau hauv loj hlob. Nws tseem yuav mus yuav nthuav kom pom ntau npaum li cas ntxiv lub ntiaj teb no yuav thawb nws tshaj tom ntej 100 xyoo.
Thaum Seiffert Muaj, peb paub txhij txhua nyob rau hauv muab tuam txhab uas muag laser kawm tuab si lug systems raws li zoo raws li lwm yam kev cov cuab yeej uas yuav pab lawv ua raws li lawv cov khoom thiab khiav. Yog hais tias koj xav mus kawm yuav ua li cas koj lub tuam txhab yuav pab tau los ntawm kev siv lasers, hu rau peb ntawm 800-856-0129 hnub no.
