Rau cov neeg ntawm koj uas tsis paub LASER yog ib qho lus luv luv rau lub teeb Amplification los ntawm Stimulated Emission of Radiation.Lub laser tau tsim nyob rau hauv 1960 los ntawm American physicist Theodore H. Maiman, tab sis nws tsis yog kom txog rau thaum 1967 uas Hungarian tus kws kho mob thiab kws phais Dr. Andre Mester tias lub laser muaj qhov tseem ceeb kho tus nqi.Lub Ruby Laser yog thawj lub tshuab laser puas tau tsim.
Ua haujlwm ntawm Semelweiss University hauv Budapest, Dr. Mester nrhiav pom tias lub teeb qis ruby laser tuaj yeem rov ua plaub hau hauv nas.Thaum lub sij hawm ib qho kev sim uas nws tab tom sim rov ua dua ib txoj kev tshawb fawb yav dhau los uas pom tias lub teeb liab tuaj yeem ua rau cov qog nqaij hlav hauv nas, Mester pom tias cov plaub hau rov qab sai dua rau cov nas kho dua li cov nas uas tsis kho.
Dr. Mester kuj tau tshawb pom tias lub teeb liab laser tuaj yeem ua kom cov txheej txheem kho qhov txhab ntawm cov nas nyob hauv cov nas.Tom qab qhov kev tshawb pom no nws tau tsim Lub Chaw Tshawb Fawb Laser ntawm Semelweiss University, qhov chaw nws ua haujlwm rau nws lub neej.
Dr. Andre Mester tus tub Adam Mester tau tshaj tawm nyob rau hauv ib tsab xov xwm los ntawm New Scientist xyoo 1987, qee qhov 20-xyoo tom qab nws txiv qhov kev tshawb pom, tau siv lasers los kho 'lwm yam tsis tuaj yeem' rwj."Nws coj cov neeg mob xa los ntawm lwm tus kws tshaj lij uas tuaj yeem ua tsis tau ntxiv rau lawv," tsab xov xwm nyeem.Ntawm 1300 kho kom deb li deb, nws tau ua tiav kev kho mob hauv 80 feem pua thiab kev kho ib nrab hauv 15 feem pua. "Cov no yog cov neeg uas tau mus ntsib lawv tus kws kho mob thiab pab tsis tau.Tag nrho tam sim ntawd lawv tau mus ntsib Adam Mester, thiab tag nrho 80 feem pua ntawm cov neeg tau kho zoo siv lasers liab.
Interestingly, vim tsis muaj kev nkag siab txog yuav ua li cas lasers muab lawv cov txiaj ntsig zoo, ntau tus kws tshawb fawb thiab cov kws kho mob thaum lub sijhawm tau suav tias yog 'magic.'Tab sis hnub no, peb tam sim no paub tias nws tsis yog khawv koob;peb paub raws nraim li cas nws ua haujlwm.
Hauv North America, kev tshawb fawb lub teeb liab tsis tau pib tuav mus txog thaum xyoo 2000. Txij thaum ntawd los, kev tshaj tawm kev tshaj tawm tau loj hlob yuav luag exponentially, tshwj xeeb tshaj yog nyob rau xyoo tas los no.
